What's the best Audio format to use in Unity?

Unity Engine
1

I am working on a project and my target platform is mobile and I have quite a few sound files to add. In the hundreds. I do have a audio converter and for best performance I want to use a format that is best optimized for mobile, but still keeping good sound quality Most of the audio clips are 30 secs or less and are looping audio. With a few exceptions of a few being over 3 minutes.

Here are the list of formats I can convert to

AAC- Advanced Audio Coding (*.acc)
AC3- Dolby Digital AC-3(*ac3)
Flac-Free Lossless Audio Codec (flac)
Mp3- MPEG Layer-3 Audio (.mp3)
m4A- MPEG-4 Audio (.m4a)
OGG-Ogg Vorbis Audio (.ogg)
WAV-Waveform Audio (*wav)
ALAC-Apple Lossless Audio Codec (*alac)

Thanks :slight_smile:

Thanks, and that’s ok :slight_smile: Texture format I just use .jpg and regular normal maps. Those are ok right? I noticed .tga is used quite a bit and is those better than .jpg’s of tiff files?

Don’t use .jpg; it’s a lossy format. Use a lossless format like .psd or .png. That goes for audio as well…don’t use lossy formats. If you use compression in Unity, then you have compression on top of compression. The exceptions being .ogg or .mp3, which are used as-is, depending on platform. It would be a good idea to read the docs.

Hmmm never thought of it that way :wink: A great majority of my textures already came in .jpg format, so would it be possible to covert them to .psd or .png format with PS? Although I’m not sure that will makeany difference since they started out as .jpg. I’ll go read it right now.

Right, if they were .jpg at any point, the information was already lost so converting to another format won’t do any good.
