AudioRoo

AudioRoo is a simple, powerful audio format converter for macOS.

Drop files or folders into the pouch and click convert: it’s that easy to hop between formats.

• Runs entirely on your Mac. Nothing uploaded, nothing collected, nothing tracked
• Batch process entire folders or libraries with a streamlined workflow
• Use the default settings, or fine-tune options like sample rate, bitrate, and channels when you need more control
• Keep folders intact or flatten them, save favorite output destinations, and preview exactly which files will be converted in the queue
• A command monitor that shows the exact FFmpeg command for your chosen settings

AudioRoo is powered by current FFmpeg 9+ builds, so you get the most recent improvements. No ancient encoders here. The result is a fast, responsive converter that feels quick with single files and scales effortlessly to large batch runs or big audio libraries.

For free users, MP3 conversion, including advanced settings and batch processing, is unlimited and costs nothing. Free users also get 15 free conversions in every premium format. A one-time in-app purchase unlocks unlimited conversion across all supported formats.

Supported export containers include:
MP3, OGG, WAV, M4A, FLAC, AAC, AC3, MP4, OPUS, WMA, AIFF, CAF, WV, MP2, TTA.

AudioRoo accepts almost any container format as an input: if there is audio data, AudioRoo will try to find it!

AudioRoo uses FFmpeg, FFprobe, LAME, mpg123, libsoxr, libogg, libvorbis and libopus under various open-source licenses. Details and library source code can be found on the support page. Screenshot pattern wallpapers courtesy of The New York Public Library.
