Convert vintage Atari ST and Falcon Audio Visual Research audio files (.avr) into standard 16-bit linear PCM WAV directly in your browser. 100% private in-browser decoder.
Detailed side-by-side format architecture for AVR Sound Stream / Module (.avr) and Waveform Audio File Format (.wav). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .avr file onto the working surface or use the system file dialog. File magic bytes are verified locally on device.
Select a quality preset (Lossless, Visually Lossless, Balanced, Smallest) or adjust advanced encoding switches in the options panel.
Click CONVERT to execute local WebAssembly compilation. Save the finished .wav directly to local storage, or stage it for chaining.
Prefer local shell scripting? Run this standard POSIX command on your machine to achieve equivalent transcoding without a web interface:
# Convert AVR to WAV locally
ffmpeg -i input.avr -codec:a pcm_s16le output.wavWorking with files across multiple web pages? The official convrtr Chrome Extension adds native Side Panel docking, right-click context menu media extraction, and visible viewport capture. Powered by the same zero-upload client-side WebAssembly engine.
A technical comparison between Atari ST Audio Visual Research (.avr) sound files and standard RIFF WAV. Understand 128-byte headers, Motorola big-endian PCM, and modern playback.

The AVR (Audio Visual Research) format was developed in the late 1980s for the Atari ST and Falcon030 computers. Built for professional sound sampling, digital synthesis, and early hard-disk audio recording, AVR files feature a 128-byte header starting with the '2VRH' signature, followed by raw 8-bit or 16-bit big-endian PCM audio samples.
Modern operating systems, mobile devices, and digital audio workstations (DAWs) cannot natively open vintage Atari ST audio files. Converting to standard 16-bit linear PCM RIFF WAV allows musicians, sound designers, and retro computer enthusiasts to play, sample, and edit vintage ST recordings on modern systems.
Yes! convrtr supports both mono and stereo AVR files across 8-bit (signed and unsigned) and 16-bit (big-endian signed and unsigned) sample configurations, automatically converting them into standard little-endian PCM WAV.
Never. All byte parsing, signedness conversion, big-endian to little-endian transposition, and WAV container encoding execute 100% locally in your browser memory. No audio is ever uploaded.
AVR Sound Stream / Module (AVR) and Waveform Audio File Format (WAV) serve distinct roles across the digital workflow. Converting to WAV provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (WAV) is inherently lossless or supports lossless operation. Your original visual or audio fidelity is mathematically preserved without quantization artifacts.
Never. convrtr is architected with a strict zero-upload model. All processing, decoding, decompression, and encoding happen 100% locally on your machine using sandboxed WebAssembly and Web Workers. Your data never touches an external server, database, or analytics collector.
You can execute this conversion locally via command-line utilities such as ffmpeg, cwebp, or ImageMagick. For example: see the developer terminal recipe provided in the technical specifications dossier above. convrtr provides the identical local-first capability directly inside your browser without installing CLI packages.
Yes. You can drop multiple .avr files into the instrument to process them concurrently in browser Web Workers, or click 'Open in Master Studio' to queue mixed formats, configure individual targets, and export as a single ZIP archive.
