I don't see anything on a file's page to indicate stereo or mono in the Audio Spec section.


Should there be?

If you record on more than one channel then use Stereo.   Simple things recorded with one lone mic like simple sound effects can be uploaded in mono at 44.1 or 48khz 16bit.


 


I´m guessing voice also is a candidate for mono since if you don´t add instumental tracks you can upload just that. A laugh is a good example.

for the buyer it probably doesn't really matter because they will most likely choose whether the final program will be mono or stereo.  The only thing is that the contributor needs to make sure that his stereo files will still sound balanced and good quality when converted to mono---  sometimes stereo arrangements run into big problems in mono.

I record all sound effects in stereo. (Two mics) For example my motorcycle effect uses two mics and you hear the motorcycle leaving in the right channel fading into the left.  The level in both is good but the stereo effect adds a little something IMO.  As a former radio commercial producer I always used panning effects when they were available. Vocals are almost always recorded in mono with the right and left channel being equal.


One thing to remember however is a producer can adjust the panning or even add panning when her or she is putting a piece together.  I think music should always be in stereo.  Everything else can be mono without making a huge difference.  But if you have the ability to record efx in stereo you should.  It’s way easier to convert a stereo to mono rather the mono to stereo.

Stereo or mono - what we have to remember is that there are many files that will be stereo however essentially have the same information on them and therefore be mono. It is important for buyers to listen to the sample and hear if it is stereo or mono, as we do not want to misrepresent a mono file as being stereo just because it has two channels.


Also, remember that if you are recording in stereo to watch for phase cancelation, where the sound reaches mics at a different time, creating sound waves that can fully or partially cancel each other out. This can take some practice but a x/y stereo mic configuration goes a long ways to fix these problems. Also as I do (I usually prefer not to use xy configurations), you can manually fix phase problems by matching up waveforms in post.
