Adjust the following performance-related Unity settings and follow these guidelines to prevent audio-related impacts on your app's performance.
- Limit simultaneous audio sources to avoid CPU spikes.
- Enable spatial audio only on nearby sounds - use panning for distant sounds to reduce CPU load.
- Avoid streaming from compressed Asset Bundles (even with LZ4) when dealing with music. The decompression overhead will cause high, spikey CPU usage that severely impacts performance.
In your Unity's project's audio settings, enable Load in Background and set the Load type to Decompress on Load to force the audio to pre-load.
