Hi, Thank you for the audio and the code. Could I please grab your FMOD and Unity versions? While I investigate, I will pass on some forums with useful information: Solving some VOIP issues: > [@Vivox to Unity OnAudioFilterRead to FMOD programmer sound. Stutters/crackling](https://qa.fmod.com/t/vivox-to-unity-onaudiofilterread-to-fmod-programmer-sound-stutters-crackling/21235/15): > > Hi everyone, I was having the same audio stuttering problem when sending Vivox signal to FMOD with AudioTaps. I tried so many times with different approaches and was about to give up when I finally fixed in our game. The catch was actually using what Connor said in a previous post about using an intermediate audio buffer and setting the proper CREATESOUNDEXINFO. I currently have Unity Audio settings with buffer size at Best Performance (which is 1024) and default settings. I implemented Latency… Play back audio with minimal delay: > [@Audio artifacts when playing audio generated via code](https://qa.fmod.com/t/audio-artifacts-when-playing-audio-generated-via-code/22880/4): > > 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\_SOUN… We also have our [Unity Integration | Examples Video Playback](https://fmod.com/docs/2.02/unity/examples-video-playback.html) which outlines how to deal with provider/receiver audio. --- _[View the full topic](https://qa.fmod.com/t/sandy-noise-while-streaming-audio-voice/23179)._
