Yeah, a loop back Brennan, with what others suggested some up's and downs but also a longer topic to explain to set there local to 0db and track if in reaper to 0db and to ignore how loud it sounds there end and to reduce master if it becomes too loud then to follow onscreen tips.
Like play a long not, then hard, then soft, from this a formula could be worked out then user can be show levels for 3 tests and advised say to reduce volume on instrument so it appears say for instance 13db less on the local channel peak meter.
reason for soft say pluck of a string as well as normal and loud it allows for min, norm and max to be discovered which will help if someone is over gained.
If all 3 are close they will be over gained and instructions can be given to fix over gained input.
Also playing back there sound after the test so like saved local to server, test of 3 parts finish then it says something like type /play to hear a record of what they just played.
or say /live to have it looped back live, also maybe voice mode could be used for this but maybe in a little higher quality than voice is in.
/restart would be cool too in case it goes wrong and people can restart the test. But remember to del the mp3 it saves if they restart. :P
Maybe in future Reapers if could have a audio level setup feature to perform it local.
You could also add some fun features like make a Sample so they type /sample then when it finishes it gives a link to download the sample, this would need ftp access or local save to http folder if people have a webserver too. Could be a fun thing, people could sample a song or a funny quote then maybe a folder could with cfg could be pulled into ninjamcast and people can like if enabled type /sample list then say /sample bonkers and it would play a sample say someone recorded on there and called bonkers.
Actually as its got this deep why not add options to ninjamcast then any server can have test abilities, if you do can I ask one thing, that test can be enabled between Times so it auto turns off the option after say 5pm and back on again say 10am etc.
I could see ninjamcast growing into a must have addon for Ninjam.
I love NINJAMCAST and that you made it available for all Brennan.
