AMR – Adaptive Multi-Rate audio
AMR is a speech codec used for voice recordings and voicemail on mobile phones. Files are very small and tuned for speech, not music.
More AMR conversionsHow this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
