Frequently Asked Questions
Common questions about our online audio editor.
Is this audio editor really free?
Yes, completely free with no hidden costs. All features including trim, merge, speed change, volume adjustment, and format conversion are available without registration or payment.
Is my audio file secure and private?
Absolutely. All processing happens locally in your browser using WebAssembly technology. Your files never leave your device and are never uploaded to any server.
What audio formats are supported?
We support input of MP3, WAV, FLAC, OGG, M4A, and AAC files. You can export to MP3, WAV, FLAC, AAC, or OGG formats after editing.
Can I merge multiple audio files?
Yes, the Merge tool allows you to combine multiple audio files into one. You can reorder files by dragging and add as many files as needed.
What is the maximum file size supported?
There is no strict file size limit since processing happens in your browser. However, larger files (over 200MB) may take longer to process depending on your device performance.
Does the speed changer affect audio pitch?
Yes, changing the playback speed also changes the pitch. At 2x speed, the audio will sound higher pitched, and at 0.5x it will sound lower. This is normal behavior for speed adjustment.
