Just got my first sound effect pack reviewed and I found out that mono is not approved. But it makes no sense to bounce stereo files from a mono sound. It only doubles the size of the file. Is there a proper reason to not allow mono files in the sound effects category?

Also it is a lot faster to export mono files as mono files out of Pro Tools when you can have hundreds of different mono sounds that need to be bounced one at the time if I want to make them stereo files, whereas mono sounds that have all processing done and have been named properly already only need to be selected and exported with a couple of clicks.

As a customer I’d certainly want to get mono sounds as mono files to avoid having to convert stereo files into mono files myself and to save hard drive space.

Also, if inappropiately summed in mono the stereo file can cause severe clipping distortion in some software when the in-phase signals from two channels are summed to one channel. And if the customer doesn’t understand basic principles of audio, then there can be cases where the sound will be distorted without them ever noticing it.

Maybe it has something to do with the watermark.

Can’t be because the preview was stereo 320kbps and all files in the main item are 44.1khz 16-bit and obviously don’t include the watermark. The reason for rejection was quite clearly stated: “The files need to be stereo.”

Interesting, because I heard that in some cases buyers prefer mono sounds and even prefer the ability to run a sound or track in mono. Stereo is not always needed or preferred, as crazy as that sounds.

Probably AJ wants to standarize submissions. BTW stereo is better than mono, because you may always change stereo to mono. In opposite direction you change only format not a sound.

Any serious, professional game developer will, or at least should, never use stereo sound effects. In fact, they’d stay far, far away from MP3 as well. From the perspective of serious, professional game development, the presence of MP3-format game sound effects here is unprofessional, and nonsense to say the least. Evenmore so for loops, on which I’ve already elaborated before. Now that it’s being mentioned: so is the presence of stereo game sound effects. It shouldn’t be so that clients are expected to audio-proces the items themselves (e.g. from stereo to mono). There should at least be an option to include mono-versions. All in all, this says a whole lot about the type of market/developers Envato aims for, and which not. Take your advantage of that knowledge.

I regret having uploaded a few game sound effects myself when I was very new here. Having a history of game development, it makes me look silly in the eyes of the people I know.

True stereo, 2-channel audio is very different from having mono sound in a stereo file. You could, in theory and practise, make a 8-channel wav-file for 7.1 surround sounds, but it makes no sense if the sound is supposed to be 1-channel mono sound.

Stereo files are only needed when the sound is using both channels as in music that is mixed in stereo or sounds that are recorded using stereo micing techniques.

There’s already a support to use 1-channel files here. It is just not allowed here. I would suggest a change to this policy, because the mono soundfx items should not need converting from 2 channel to 1 channel wave-files by customers. There’s a possibility that something goes wrong if someone without proper knowledge uses these files without converting or converts them in an unsuitable way. For example: If I normalize the mono-stereo sound file close to digital zero and someone converts the mono sound in a stereo file into a single channel mono file using software that takes both channels and sums them together, the sound of the resulting file will have clipped samples and will sound bad. The right way to convert would require splitting the stereo file into two mono files and using one of them.

Mono sound in a stereo file is basically the same as having 2 identical mono files playing in sync with each other.

Also, in theory, if any development company with some knowledge in game design, could convert a Mono sound into a stereo, it’s just a matter or track splitting, copying and manipulating (probably decreasing the level). And, actually it would probably be easier to get the desired effect to go from mono to stereo in this way, than to go from stereo to mono. Albeit, I have no technical training in sound design, but what I have learned from my own experimentation and curiosity—and reading online here and there.
