Recording Behaviour

Simply add the WavRecorderBehaviour to any GameObject to enable recording.

This will stream the recording directly to disk as it is recorded.

Audio Clip Extensions

Provides extensions to encode AudioClips to WAV encoded bytes. Supports 8, 16, 24, and 32 bit sample sizes.

Encode WAV

Encodes an AudioClip to a WAV formatted byte[] or NativeArray<byte>.

Warning

The resulting NativeArray<byte> must be disposed of manually to avoid memory leaks, you can adjust the allocator type by passing in an optional parameter.

byte[] bytes = audioClip.EncodeToWav();
using NativeArray<byte> bytes = audioClip.EncodeToWavNative();
byte[] bytes = await audioClip.EncodeToWavAsync();
using NativeArray<byte> bytes = await audioClip.EncodeToWavNativeAsync();
