Flash to Atari Audio

Extract SWF audio into AVR — the Audio Visual Research format used on Atari ST systems and retro computing platforms.

Server Conversion

Our cloud infrastructure handles the SWF decoding and AVR encoding. No Atari software needed on your machine.

Secure Processing

SWF files are deleted post-conversion. AVR outputs are automatically removed within 24 hours.

About formats

SWF (Small Web Format, originally Shockwave Flash) is a file format for multimedia, vector graphics, and interactive content created by Macromedia in 1996 and later developed by Adobe Systems following the acquisition of Macromedia in 2005. SWF files contain a combination of vector and raster graphics, animations, embedded audio and video, and ActionScript code for interactivity, all packaged in a compact binary format designed for efficient web delivery. During its heyday from the late 1990s through the early 2010s, SWF powered a vast ecosystem of web content including animated websites, banner advertisements, casual games, educational applications, and interactive multimedia experiences. The vector-based rendering engine allowed smooth animations and scalable graphics at remarkably small file sizes, making rich multimedia content practical even on slow internet connections. SWF supported progressive rendering, allowing content to begin playing before the entire file was downloaded. Adobe Flash Player at its peak was installed on over 98% of internet-connected desktop computers, giving SWF an unmatched reach for interactive web content. The format evolved to support video playback, camera and microphone access, 3D acceleration, and socket connections for real-time applications. Adobe ended Flash Player support in December 2020, but SWF files remain historically significant and are preserved through open-source projects like Ruffle that enable continued access to this era of web content.
Initial release: 1996
AVR (Audio Visual Research) is an audio format that originated on the Apple Macintosh around 1989, created by the Audio Visual Research company for their editing and synthesis tools. It stores raw audio samples preceded by a fixed-length header containing sample rate, bit depth (8 or 16 bits), channel configuration, and loop point markers. Unlike complex container formats, AVR uses a flat binary structure with no compression, preserving the full waveform quality at the expense of larger files. The format served professional Macintosh audio workstations during the late 1980s and early 1990s, when the Mac platform dominated creative computing. One advantage is uncompressed storage guaranteeing zero artifacts and perfect signal integrity through editing operations. Native loop markers represent another feature, letting sound designers define seamless repetition points within the file — ahead of its time for sample-based music production. Tools like SoX maintain AVR support, ensuring archivists can access and convert these legacy recordings. While eclipsed by WAV and AIFF, AVR remains a notable piece of early digital audio history.

Frequently Asked Questions

Why convert SWF to AVR?

AVR (Audio Visual Research) is a format from Atari systems. Convert SWF audio to AVR for retro computing and preservation work.

How do I play AVR files?

SOX, Audacity, and Atari emulators can handle AVR audio. It is primarily a tool for retro computing enthusiasts.

Is AVR still relevant?

AVR is a niche retro format used for Atari ST audio preservation. For general audio use, WAV or MP3 are more appropriate.

What quality does AVR support?

AVR supports standard sample rates and bit depths. Quality is adequate for most SWF audio content extraction.

Do I need Flash Player?

No. All processing runs on our servers. Upload the SWF and receive the AVR without any Flash software.
