Thank you for the project, it greatly helped in testing! Some things I tested: - Artifacts - Moved the `CaptureFrame()` function from `Update()` to `FixedUpdate()` to remove the dependence on frames. - Decreased the size of the default `DSP Buffer Length` ([Unity Integration | Settings DSP Buffer Length Settings](https://fmod.com/docs/2.02/unity/settings.html#dsp-buffer-settings)), I tested `256`. - Latency - Reducing the size of the buffer created in the `exinfo` `exInfo.length = SampleRate * PCMMultiplier;`, I tested halving this value. Another option maybe using a `FMOD_SOUND_PCMREAD_CALLBACK` ([FMOD Engine | Core API Reference - FMOD\_SOUND\_PCMREAD\_CALLBACK](https://fmod.com/docs/2.02/api/core-api-sound.html#fmod_sound_pcmread_callback)) which would further decouple the recording from the frame rates and more closely attach it to the FMOD system. > [@hardsmoke](#): > > In my 4th question I mean that if a freeze occurs when starting playback (to debug it can use method with ContextMenu attribute - it will cause the game freeze), then the playback delay will increase - this is solved by compensating for the delay, you just need to wait a while. Thank you for the explanation. Let me know if that makes a difference! --- _[View the full topic](https://qa.fmod.com/t/audio-artifacts-when-playing-audio-generated-via-code/22880)._
