FAQ

Does the runtime need FFmpeg?

No. FFmpeg is only used by the Audio Studio editor window for a few extra features (LUFS normalize, time-stretch, saving edits as OGG / MP3 / FLAC, reading compressed clips). Everything else, and the whole runtime, works without it. See FFmpeg.

Which render pipelines are supported?

Built-in, URP and HDRP. The runtime and the editor windows do not render anything. The demo speaker switches to the materials of your pipeline when the scene plays; to make the Scene view match, run Tools › NIX Audio › Rebuild Demo Scene. See Demo scenes.

The demo text is invisible.

Import TextMeshPro's essentials once: Window › TextMeshPro › Import TMP Essential Resources.

Does it work with Enter Play Mode Options (Domain Reload disabled)?

Yes. Static state is reset on every Play, and this is covered by tests on Unity 2022.3 and Unity 6.

Does it work on WebGL?

Playback, libraries and markers do. The analysis functions (spectrum, bands, AudioReactive) rely on Unity's GetSpectrumData / GetOutputData, which return no data on WebGL, so meters read zero there.

Can I use it with Addressables?

Yes. Load the AudioLibrary through Addressables, then call AudioPlayer.Instance.Load(library), and keep the library and its clips in the same Addressables group. See Where to call Load / Release.

Will Audio Studio change my audio files?

Only when you apply a Trim, Volume or Speed edit. Back up original is on by default and copies the file to Library/NIXAudioBackup/; Restore latest backup brings it back. Metadata and markers live in the library asset and never touch the audio file.

Can I delete the Demo folder?

Yes. Nothing outside NixAudio/Demo depends on it.

How precise are markers?

One frame: callbacks run in the player's Update (about 16 ms at 60 fps).
