Please select a longer segment.","Which formats are supported? Why might the waveform fail to load?","Common formats such as MP3, WAV, AAC\u002FM4A, OGG, and FLAC usually decode in the browser and show a waveform. If a file cannot be decoded (unusual codec or corruption), try another format or browser — the page will show a clear message.","What does “after upload (optional)” mean?","Below the upload area you can pick: edit only, smart trim silence, trim start & end silence, or peak normalize. Your choice runs automatically once after the file is decoded, updating selections or the normalized buffer. The same pill buttons are available later in the editor to re-apply.","How do I trim and export?","Select regions on the waveform (multiple clips allowed), drag boundaries, fade handles, and the volume line as needed. Use Preview all segments, then choose MP3 or WAV (bitrate for MP3) and Export to download.","Quick actions vs Silence Detection?","Quick actions use tuned presets for common jobs: multi-clip speech, trim outer silence only, or peak normalize. Expand Silence Detection to adjust threshold, minimum silence, and padding for fine control. You can use both.","Is my audio data secure?","Yes. Decoding, visualization, and export run locally in your browser. Files are not uploaded to our servers — suitable for interviews, voiceovers, and unreleased material.","What keyboard shortcuts are there?","Space: play\u002Fpause. Arrow keys: seek about ±5 seconds.
