If you keep it at 16 bit then dithering is not needed...dithering is only from 24 bits down to 20 or 16 bits.

Hello, Just wanted to add that you only ever need to add dither if you are decreasing the bit rate. If you convert a 16bit file into 24, for example, dither is not necessary.

At what bitrate does your app process audio?

If it processes the audio at a higher bitrate than 16 then you need to add dither even if your session is at 16.

Don't know? Throw the dither plug on your master fader after T-Racks and listen to the quiet passages, and reverb tails. Does it sound better with or without?

Don't know much about T-racks but if it can accept a file at 24 bit then I would recommend exporting your files at 24 bit. Keep them at a high bit rate and only bring it down to 16 bit after processing it in T-racks. Processing will generally sound better if done at a higher bit rate. I don't know what sort of dithering T-racks uses. If it's bad then disregard my advice.

T-racks is an "analog mastering" stack of virtual processors. I have heard mixed reviews but in my own personal experience I get the results I am trying to achieve (when you adjust something you hear it for sure). It can work in 24bit and 16bit (depending on the version you have I think). The dither on it doesn't leave a bad taste on the final product but if someone out there has waves gold for instance and t-racks maybe they could do a shootout comparison on the dither and let us know what happens. Thanks
