Unity3D optimization tips

Some code allocates memory when running in the editor and not on the device. This is due to Unity doing some extra error handling so possible error messages can be output in the console. Much of this code is stripped during build. It's therefore important to profile on device, and do it regularly.

Optimizations often makes code more rigid and harder to reason. Don't do it until you really need to.

When profiling, wrap methods or portions of a method in Profiler.BeginSample(string name) and Profiler.EndSample() to make them easier to find in the profiler.

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
