About formats

VQF is the file extension for audio encoded with TwinVQ (Transform-domain Weighted Interleave Vector Quantization), a lossy compression technology developed by NTT (Nippon Telegraph and Telephone) in 1994 and later commercialized by Yamaha under the SoundVQ brand. The codec claimed a 30 to 35 percent size advantage over MP3 at equivalent perceptual quality — a 96 kbps VQF file was said to match a 128 kbps MP3 — generating considerable excitement during the late-1990s format wars. TwinVQ supports constant bitrate encoding at 80, 96, 112, 128, 160, and 192 kbps, and the underlying algorithm was incorporated into the MPEG-4 Audio standard (ISO/IEC 14496-3) as one of its defined object types. Despite strong technical merits, VQF never achieved widespread adoption: encoding was slow compared to MP3, hardware player support was scarce, and the proprietary licensing discouraged third-party development. In 2009, the FFmpeg project reverse-engineered the TwinVQ decoder, bringing playback support to VLC and other open-source players. VQF stands as a notable case study in codec history — technically ambitious yet eclipsed by MP3's ecosystem momentum and the later rise of AAC.
Initial release: 1996
MAUD is an audio file format developed by MacroSystem for the Commodore Amiga platform, introduced in the early 1990s as part of their digital video and audio production tools. Built on the Amiga IFF (Interchange File Format) chunk architecture, MAUD files organize data into clearly delineated chunks — MHDR for the header, MDAT for sample data, and optional annotation chunks for metadata. The format supports mono and stereo layouts with bit depths of 8 or 16 bits and sample rates up to 48 kHz, which represented professional-grade specifications on Amiga hardware. Both signed linear PCM and A-law/mu-law encodings are available, offering a choice between fidelity and file size. MAUD saw primary use in the Amiga video production community, where MacroSystem Retina and VLab Motion boards demanded synchronized audio that the standard 8SVX format could not deliver. Conversion support exists today through SoX and libsndfile, ensuring vintage Amiga productions remain recoverable. Three distinct advantages stand out: clean IFF-based structure that any chunk-aware parser can navigate, 16-bit stereo capability ahead of typical Amiga audio, and lightweight overhead that left maximum CPU headroom for video rendering.

Frequently Asked Questions

What is MAUD?

MAUD is a specialized audio format — the 16-bit Amiga audio format for retro computing.

Why convert VQF to MAUD?

VQF is a dead format with no player support. Converting to MAUD rescues your audio for specific applications that need this format.

What handles MAUD?

Specialized tools, SoX, and targeted professional software support MAUD audio processing and playback.

Is there quality loss?

VQF is lossy — the original quality loss is permanent. The MAUD output preserves whatever quality the VQF file contained.

Is the conversion secure?

VQF uploads are deleted immediately after conversion. MAUD results are removed from servers within 24 hours.
