7 toolsEdit and create
Merge audio files
Put several tracks one after another into a single file. Sample rate and channels are matched automatically.
MP3 Compressor
Pick a lower bitrate and the file shrinks accordingly. 320 kbps is near-transparent, 128 is the classic size, 96 fits almost any inbox.
Audio Trimmer
Set a start and an end and keep only that part. Works with MP3, M4A, WAV, OGG and FLAC.
Normalise audio volume
Bring quiet recordings up to a usable level — and a whole batch to the same level, so you stop reaching for the volume knob between files.
Convert and export
Extract Audio from Video
Pulls the sound out of a video and saves it as an audio file. Everything happens on your device.
Audio Converter & Trimmer
MP3, M4A, WAV, OGG and FLAC. The file is decoded and written again on your device — nothing is uploaded.
Video to MP3
Turn the sound of a video into an MP3. Drop the file, pick a bitrate, done — all on your device.
