No problem. Implemented and released in v1.5.0 (updated ReaPack and Stash ZIP).

I had to tidy the dials up to make room for it, but note the new "Amount" control:



EDIT: it now hides the Q and Amount knobs until you hit "Correct", because they don't do anything until that point.

It scales the correction curve (white) but not the bands - that seemed (to me) the more intuitive and clear way to display what it was doing.

The built-in wet/dry dial probably wouldn't give you the result you want because:
  • phase issues mean things don't add up right (true for any EQ that's not explicitly linear-phase)
  • even without phase issues, a linear mix doesn't give nice (or even symmetrical!) dB interpolation. For example, a 50% wet/dry mix of a +10dB boost is +6.4dB, but a 50% wet/dry mix of a -10dB cut is -3.6dB.

Have fun!

Hi Geraintluff

No problem. Implemented and released in v1.5.0 (updated ReaPack and Stash ZIP)."

Hmmm ... I tried updating via ReaPack ... and tried the direct ZIP links.

When launching Spectrum-Match ... it does not seem to be the v1.0.5 that has the new feature ?!?

----- EDIT ---
Nevermind ..... Amount knob shows AFTER 'Correct'.

Will test this out ..... THANKS !!

Hi,
The RealPack version of the Spectrum Matcher doesn't show the new knob.

Also, please update the Author field in ReaPack - most of them show up as Author Unknown, and makes them difficult to find. Thanks!

See my post above ...

The AMOUNT knob doesn't show UNTIL you click CORRECT.

Sorry for the confusion - yeah, I hid it (and the "Q" dial) until it's actually correction, because those dials don't do anything otherwise.

I was hoping that it would make it easier to use for new users, by making it clear that the "amount" dial was only relevant to the correction filter, but if it's confusing I can put them both back.

(Also, thanks for the tip on ReaPack "author" field - should be fixed now. I'm working on putting in descriptions for them too - please let me know if this doesn't work!)

Default New effect: Vibrato

I've added a new effect: Vibrato (main website)

It's a pretty simple one - it adds vibrato by detuning/delaying the audio, but instead of a constant LFO, it uses MIDI notes to produce a more natural envelope.

This is most useful for adding vibrato to synths that don't have already have it - for example, adding vibrato to ReaSynth or Hammer and Chord.



The "lookahead" dial adds latency - without this, the start of a note might be detuned due to ongoing vibrato from a previous note.

Default New effect: Cross-Polyphonic FM

One more effect, based on some tinkering I did while on holiday - I couldn't think of a good name, so it's called Cross-Polyphonic FM (main website, audio demo with Hammer and Chord).

This is a MIDI-controlled frequency-modulator. You can add it after an existing synth, re-using the same MIDI notes to change the character of the sound, or have unrelated MIDI notes.

Multiple MIDI notes produces multiple modulation frequencies, but the notes aren't processed separately - they are added together to form a single modulation signal. This means that all the different notes interact, so open chords work well if you want it to sound tonal (similar to distortion).

Hi Geraint!

Just wanted to say thanks for the spectrum matcher, and give you a challenge regarding it. Often times, I have the need to alter the mids, but want to keep the existing low end, or vice-versa.

It would be *really* useful to be able to right-click a band and disable the frequency matching for that band.

I'd happily donate for this feature.

Neat idea! Disabling individual bands could be fiddly - what would you think about a range control (or high/low dials) to determine which bands were active? I think it would be cleaner. Frequencies outside that range could be left alone or trimmed (highpass/lowpass) according to a setting.

I just spent a good deal of time trying to get a huge low end bump out of an otherwise proper sounding curve... range sliders would be really nice, preferably with variable slope if possible.

If I may add another FR, I'd find it useful if the Gain parameter only affected the Wet (Amount >0%) signal, so you could level match and use the Amount slider with less loudness bias.

I'm not sure though if the Amount is just a simple dry/wet or an interpolation of the band gains? Would this be feasible in the latter case? Also this might break existing projects?

EDIT: Wait, I can just use Reaper's dry/wet knob for this, right?

PS. Thank you for these awesome plugins!

That sounds great - whichever is easiest!

Hey, not sure what caused it, but I ran two instances of spectrum matcher on the master bus, for A/B'ing with one active, and when I re-opened the project there was a loud roar until I turned off the one active spectrum matcher. Never had that happened with just one instance, but was able to repeat the problem.

"Amount" interpolates the gain (in dB). You shouldn't use the built-in wet/dry knob - it won't add up correctly because of phase shifts. (This is true for ReaEQ and most other EQs as well.)

That's not great, I'll have a look - sorry about that.

Do you think it might have been "active" but not "frozen"? If so, that's a straightforward fix.

EDIT - changed and released in v1.5.1. When you reload a corrected-but-not-frozen instance, it used to forget the analysis but still try to correct (and went a bit wrong). Now it turns correction off - just as before, if you want to keep your correction curve, hit Freeze.

Alright - this is in.

You should now be able to set upper/lower limits for the correction. You can also select the boundary type: highpass/lowpass, flat (continues from the nearest band) or zero (returns to 0dB).

Give it a whirl and let me know how it works for you.



The layout's a bit busier now, but I think tidying that up is a task for another time.

Also done. Old projects/presets should work fine.

Get v1.6.0 (or the latest ZIP) for both of these changes.

Awesome! Thank you

Good thought with the different filter modes.

One minor issue I noticed is that with low end boosts, sweeping the highpass frequency around tends to cause loud volume spikes when it enables/disables the individual bands.

Another: When the filters are set to their respective default positions (10Hz and 20kHz), their mode setting still seems to alter the curve slightly. Does the "flat" setting completely disable them in those positions?

Ooh, yeah. The issue is these dials actually change the number of filters currently active, and shuffles their order around. I'll have to think some more about what to do about this - I tried one solution but it had an unreasonable performance impact.

The defaults (20Hz highpass on the low end, 18kHz flat on high end) are equivalent to the previous version. It affects the curve slightly at the low end, but the high end should be fine.

So, it kind of depends what you mean by "disable". The filters are actually not centred on the bands themselves, but are placed on the boundaries between the bands. If you set the boundaries to "flat" then the final bands extend outwards, so there aren't any filters the very edges, which is possibly what you're thinking about.

Ah ok, yeah I was wondering what was the "default" mode.

So another idea. Do you think it might be useful to be able to invert the action of the Amount parameter, to be able to subtract a spectrum of one signal from another? Could be useful in mixing for fitting together sounds occupying the same frequencies, especially with the new filters so you could target the subtraction to the crucial frequencies.

EDIT: ^ Not sure if I'm thinking about this right.. The obtained spectrum is actually the difference of the two signals, so just inverting it would then actually only subtract the parts that already don't overlap? It'd require a different algorithm to find the overlapping areas, yes?

Related to this, are the parameters in Spectrum Matcher automatable, i. e. don't cause zipper noise? Could then use parameter modulation to dynamically change the subtraction Amount with a sidechain signal.

It would be simple to extend the Amount dial to go down to -100%. This would be equivalent to swapping the reference and the input around.

I'm not at my computer right now to add this and test it, but you can try it yourself by changing "0" to "-1" in this line (2047)
EDIT - released in v1.7.0. Amount dial now goes to -100%, and double-clicking sets it to 0.

For what you're thinking of, you could try using the combined/summed audio as the reference. If you then put Spectrum Matcher on the individual tracks, normally it would make each track sound like the combined reference - but with a negative Amount, it should make it sound less like the reference, exaggerating the most distinctive features of each track.

I don't know what the result will sound like in practice, but that's what I would try first. It's a neat idea, and I'm interested to see if it works.

I'm afraid not, for performance reasons basically. It would take about 2x CPU when automation was active. It also ~triples the time it takes to actually load/add/move the plugin (to the order of a couple of seconds on my machine).

I thought that was too high a cost given that it's not its intended use. It sounds to me like what you really want for that is a multi-band EQ with sidechain (which ReaXComp unfortunately does not support).

Possible workaround: copy the curve to ReaFIR (by hand), use wet/dry dial

I have warned against using REAPER's wet/dry dial because things don't add up linearly due to phase shifts - for example, it's possible to have a curve where the 50%/50% result reduces some frequencies below both the 100% wet and 100% dry. If the correction curve is very gentle, you might get away with it, but I don't want to recommend it.

That goes for ReaEQ as well, because the phase shifts are exactly the same.

However, if you copied the spectrum into ReaFIR, the wet/dry dial would work because it's a linear-phase EQ. There isn't a good way to copy that curve across though, it would be by hand.

Cool, I'll try that.

Good idea, I'll give it a go. Perhaps another way would be to learn one of the signals, then match white noise to that spectrum and use that curve in inverse on the other signal?

Yeah that's understandable. I like how lightweight it feels right now, especially when you freeze the curve. I haven't had the need yet to copy the curve into ReaEQ, like you suggested for possible performance increase.

I've actually used TDL Nova for this, and it's very suitable for this purpose. It even has that spectrum matching feature, but it's unfortunately not as accurate with 7 bands (also it sometimes focuses them on narrow resonances instead of the overall contour, which isn't always desirable).

Is this somehow different from how parallel EQs like Pultecs work, or is it just a feature of them? FWIW I don't always like the sound of linear phase in parallel. Pre-ringing with transients is one thing, but sometimes the phase shift might even sound "good", for example when high-passing a distorted bass track, where the cancellation cuts out some of the mud near the cutoff freq. Switching between minimum and linear phase in EQuilibrium changed the sound from "kinda hollow" to "muddy" in that particular case.

The dry path in the built-in dry/wet control unfortunately isn't latency compensated last time I checked, so it doesn't work with plugins with PDC (although I think it might be possible to work around this by compensating with the Time Adjustment Delay JSFX).

Well, I'm not completely sold on the dynamic spectrum ducking thing anyway. But a static "fitting" curve for two similiar signals might be useful in some instances. I'll go check if I can get that negative amount working.

Default Updates/releases

Fixed something that I'd wanted for a while - thanks to some wise words from Justin, presets are now shipped with the effects, and should just get auto-imported when the effect is loaded.

Other updates include a slight (15%) performance improvement to Spring Box, and a second "polar" display mode in Panalysis (where left/right are sides instead of diagonals)

Default New synth: Soft Bell

My imaginative naming scheme strikes again with Soft Bell.

This synth aims to make soft chimes and bell-like sounds (audio demo 1, audio demo 2) using individually-specified harmonics.

It can also be used with audio input - it acts like something between a resonant filter and a ring-modulator, so can produce interesting inharmonic sounds if you turn the "tonality" dial down.



There should be a couple of presets already pre-loaded when you open it. If someone could let me know if that works, I'd appreciate it. Great, thanks!

Geraint

Default Legato/Portamento support!

OK! Humonica, Hammer and Chord, Soft Bell and Cross-Polyphonic FM now have legato/portamento support.

(audio demo 1, audio demo 2)

You can configure these and a couple of other parameters in the new "config" screen:



There are two legato modes, both for monophonic lines. "Retrigger" means it closes the old note and opens a new one, bending the pitch (with optional portamento) so that they match. "Glide" doesn't trigger a new note, it keeps shifting the old one around.

The portamento control in the "Legato" section determines which notes have portamento applied. By default, only overlapping notes have portamento applied (if it is enabled), but it can be set so that all notes have portamento (from the most recent note).

EDIT 2018-06-13: added latency/anticipation to (some of) these. With legato enabled, this means the previous note changes slightly before the new note starts. This can gives a more natural transition, particularly in Hammer and Chord.

Default New Effect:

This weekend's success: Ripple, a phaser-like effect that continuously rises or falls.

(audio demo 1, audio demo 2)

This effect can sound like a phaser, but it doesn't bounce up and down - it progresses endlessly in one direction or the other. The ripples in the spectrum taper off to 0dB outside the set limits, so you can modulate some frequencies while leaving others untouched (e.g. you might not want the very low end fluctuating).

It has a variable number of filters (up to 20) with stereo offset, with two filter modes ("peak" and "notch"). Everything aside from those two parameters should be automatable.



I hope you enjoy it.

Thanks!

Forgot to reply properly to this - done, released in v1.7.0.

Damn I forgot about this too sorry

So yeah I tested the subtractive matching, and the method you proposed where you sum the two signals and then match one of them to the sum and subtract, resulted in a very subtle curve. I got a more pronounced result by matching white noise to one of the signals, then copying that to the other track and subtracting.

I only tested it for kick<->bass and got, well, quite useful results. It might work very well in some cases at least to audibly point out some of the clashing frequency ranges. Well, I'll give it a try tommorrow, thanks for the new feature!

It's really difficult to find a software phaser that actually sounds good, and this one really hits the mark again!

Default Major Humonica Update

I've just released v3.0.0 v3.0.1 of Humonica, and there are some big changes in there. I would appreciate feedback!

The two major features are:
  • "fixed spectrum" mode - instead of taking its timbre from the input audio, you can draw a spectrum with the mouse
  • "sweep" section - per-note timbre-shift envelopes to simulate filter sweeps

The combination of these two means Humonica can actually be used as a standalone synth, with no input audio required. In particular, you can produce pseudo-filter sweeps with very sharp cutoffs.

Here's an example of using it as synthesiser - every synth is Humonica, and there are no actual filters, it's all timbre-sweeps. Here's an example of filter sweeps using input audio (you can't really tell I'm saying "hello" under all that, but the natural input gives it some great timbres).



Previous presets and projects should still be compatible. Known bugs:
  • aliasing under some circumstances (I've tackled some of it, not all) - this has always been true, but fixed-spectrum mode makes it more obvious
  • might not support 192kHz samplerate - should be fixed now

I know nothing about JSFX and scripting/coding. I downloaded the zip, unpacked it and now what? Sorry if this is a stupid question, but I really would like to use these plugs, the demos sound very good.

To install from ZIP: go into the "Options" menu and select "Show REAPER’s resource path". This opens a folder where REAPER keeps various bits of configuration and extra data.

There will be a sub-folder in there called "Effects". Just move/copy the whole "Geraint's JSFX" into this Effects folder.

REAPER will find the new effects when you either close/reopen it, or if you select "scan for new FX" from one of the menus when the effects browser is open.

Here's a walkthrough video from The Reaper Blog.

Why ?
It should be available via ReaPack (as the thread title says).

Thanks. And weird -- this is what I tried first. Maybe I simply didn't see them in the JS folder. All seems good now.

Yeah, I took a quick look at that thing and understood nothing. I bet it's a great tool and everything, perhaps I'll try it out one day.

Added two "Texture" controls in case people want it to sound a bit rougher (both synth and vocoder/harmoniser mode).



(Also changed the thread title - when I started there were maybe 5 effects, but there are 20 now.)

ReaPack's understandably popular, but there's a little bit of setting up and adding repos, and not everyone's comfortable installing third-party tools.

To each their own: ReaPack is definitely more powerful, but I feel ZIP can be friendlier, particularly if you're only just dipping your toes into JSFX/ReaScripts. So I release as both ZIP and ReaPack - I actually have a handy script for it, with a slight hack to upload to the Stash.
