mne_videobrowser.browsers.AudioBrowser#

class mne_videobrowser.browsers.AudioBrowser(audio: AudioFile, playback_update_interval_ms: int = 50, parent: QWidget | None = None)[source]#

Bases: SyncableBrowserWidget

Qt widget for browsing audio with playback controls.

This browser allows interactive visualization of audio data from AudioFile objects.

NOTE: This browser currently only supports a single audio file. Methods that receive media_idx parameter ignore it and signals emit zero as the media index.

Parameters:

  • audio (AudioFile) – The audio file to visualize.

  • playback_update_interval_ms (int, optional) – Determines how often the visualization is updated during audio playback. By default 50 ms, which corresponds to 20 updates per second.

  • parent (QWidget | None, optional) – The parent widget, by default None.
