Audio converter — format, sample rate & bit depth

What is an audio converter?

Editools' audio converter changes the format, sample rate, bit depth and channel layout of your audio without uploading anything. It decodes WAV, MP3, AAC/M4A, AIFF, FLAC and OGG (whatever your browser can read), then re-encodes to WAV or AIFF — uncompressed PCM that drops straight into an NLE or DAW — or to MP3 when you need a small, shareable file. Because the work happens in your browser with the Web Audio API, your media never leaves your device.

How to use it

1. Drop one or more audio files, or click to choose them. Each file shows its format, duration, sample rate and channels.
2. Pick a preset, or set the output format, sample rate, bit depth and channels yourself.
3. Leave dither on when reducing bit depth (e.g. 24→16) and turn on peak-normalize if you want a consistent level.
4. Click Convert. Download each file, or grab them all as a ZIP.

Formats & quality

WAV and AIFF are written as native PCM at 16, 24 or 32-bit float, at any supported sample rate, mono or stereo — ideal for editing and mastering. Resampling uses the browser's high-quality engine through an OfflineAudioContext, so changing 44.1 kHz to 48 kHz (or back) stays clean and alias-free. When you reduce bit depth, triangular (TPDF) dither is added to avoid quantization distortion. MP3 export uses a selectable bitrate from 128 to 320 kbps. AAC/M4A files are accepted as input, but aren't offered as an output format because browsers can't encode them reliably.
