How do I convert AU to RAW step by step?

1. Click 'Choose File' and select your AU audio. 2. Select 'RAW' as output. 3. Adjust sample rate/bit depth if desired. 4. Hit 'Convert' and download the resulting RAW file instantly.

What is the difference between AU and RAW, and why would I convert?

AU (Sun/NeXT audio) is a container that can hold compressed codecs like µ-law or A-law, while RAW is header-less uncompressed PCM data. Converting to RAW strips all headers and codec compression, producing a pure bitstream. This is essential for embedded development, audio DSP, or when using tools that only read raw PCM. The tradeoff is file size: RAW is larger because it stores every sample uncompressed.

What technical properties are preserved when converting AU to RAW?

Our converter preserves the original sample rate, bit depth, and channel layout exactly, so you get a bit-accurate representation of the decoded audio. Any metadata or text chunks in the AU container are deliberately discarded, because the RAW format is intended solely for sample data. This prevents any hidden information from interfering with low-level analysis or playback in raw-audio players.
