I wonder if there are any bit depth experts that can help me understand whats going on. I am a hobbyist and archive my jams for ideas. Sometimes I strike on a jam that I want to polish. I'm not making any albums or professional demos. I use Sonar 5 and Soundforge 8. Sonar will work with multiple bit depth files in the same project and will render to 16/24/32 bit depths. It is my understanding that it works internally at 32 bit depth. I sometimes get a drum loop that is 16/44 and I record my guitar at 24/44. I render a master mix at 32 bit float and open and do a final mix with Sound Forge and export at 16/44. For curiosity I rendered the drum track to 24 bit and imported into Sonar. I put a bit viewer and it checked as 24 bit. I took the same loop in Soundforge and did a bit depth conversion to 24 and checked it with the bit viewer. The statistics said 24 bit but the viewer showed (and said) 16. It seems that Sonar is actually reconstructed the sound print to 24 bit and Soundforge is just adding zeros. Which brings up my 2 questions. 1. Is there any benefit at all to increasing the bit depth of a 16 bit file such as for importing it as 24 or 32 bit into Sonar? 2. Is there a benefit in exporting as 32 bit float for my final mix when the mixes source tracks are 16 and 24 bit?
