I’m using Audacity for sound editing (recommend another if you can for MAC).
My questions is what format do I save sound effects at for best results…short sounds, not music.
I’ve experimented alot but I’d like to hear about trade offs of file size and performance, etc when targeting iphones.
I’ve been saving as WAV (not MP3) mono…around 44khz 24bit…but when I export to WAV it seems to introduce a hiss.
I’d love to find out the sweet spot for audio clips so I don’t have to guess anymore.
Thanks.
Edit: I’ve just had good luck with a 44khz 16bit file…no hiss. My file was being saved as 8bit before and it produces alot of hiss.
I found it quit difficult to convert 16 bit samples in 8 bit without hiss. It was actually impossible, except for kicks. Searching on this I ended up discovering milky tracker and mod - xm file formats. There are good instruments samples for this program in mod, xm files, in 8 bit. They are (mostly) copyrighted and (regularly) copied. You can also create samples by drawing their waveforms or by using sine, triangle etc generators.
When you have some decent samples you can compose a musical phrase which will have a small memory footprint.
No hiss, much work. I also think that interpolating the samples from 8bit to 16bit will charge the iphone processor, so you gain in memory, you lose in cpu cycles. Mono samples also seem to have the same effect. If you find something else. please share.
