What audio formats are supported?

The audio player supports MP3, WAV, OGG, FLAC (in supported browsers), AAC, and M4A formats. MP3 offers the best compatibility across all browsers. FLAC support depends on your browser - Chrome and Firefox support it natively, while Safari may require conversion to another format.

Are my audio files private and secure?

Yes, completely. All audio playback and visualization happens locally in your browser using the HTML5 audio element and Web Audio API. Your files never leave your device - there are no server uploads, cloud processing, or external API calls. Perfect for personal music, voice recordings, and confidential audio.

Why doesn't my album art show up?

Album art is extracted from ID3v2 tags embedded in the audio file. If your file doesn't have embedded artwork, no image will be displayed. You can add album art using software like MP3Tag (Windows), Kid3 (cross-platform), or iTunes. The player looks for APIC frames in ID3v2 tags.

Why won't my audio file play?

Most playback issues are due to unsupported codecs. While the container format may be recognized, the internal audio codec might not be supported by your browser. Try converting to MP3 using FFmpeg: 'ffmpeg -i input.flac -c:a libmp3lame -q:a 2 output.mp3'. This ensures maximum browser compatibility.

What's the maximum audio file size?

The player supports audio files up to 500MB. This is sufficient for even very long audio content - a 3-hour podcast at 128kbps MP3 is only about 170MB. Browser memory is the practical limitation for extremely large uncompressed WAV files.

How does the waveform visualization work?

The visualization uses the Web Audio API's AnalyserNode to perform real-time frequency analysis of the audio. The 'bars' mode shows frequency spectrum (bass on left, treble on right), while 'wave' mode shows the audio waveform amplitude. The visualization is rendered on an HTML5 canvas for smooth performance.

Can I use keyboard shortcuts while audio is playing?

Yes! Full keyboard control is available: Space/K for play/pause, arrows for seeking, M for mute, L for loop, 0-9 for percentage seek, and for speed. Press ? to see all shortcuts. Keyboard shortcuts work when the audio player is focused.

How do I download the audio file?

Click the download button in the control bar to save the audio file to your device. Since all processing happens locally, you're downloading your own file - useful for saving a copy with a different filename or location.
