About formats

GSRT is a purpose-built ringtone format developed by Grandstream Networks for its line of IP phones and VoIP endpoint devices. Each file begins with a fixed-size header identifying sample rate (typically 8 kHz or 16 kHz), bit depth, and payload length, followed by PCM or mu-law encoded audio data optimized for the small speakers found in desk phones. The design prioritizes minimal decode complexity — Grandstream handsets run on embedded processors with limited memory, so the format avoids transform stages or complex bitstream parsing. Ringtones are usually provisioned through a web management interface or a centralized configuration server, letting IT administrators push branded audio to an entire fleet of phones at once. Although GSRT occupies a narrow niche within enterprise VoIP telephony, its straightforward binary layout means conversion tools can map the payload directly to WAV with minimal effort. Key advantages include rock-solid playback reliability on Grandstream hardware, negligible latency from file read to speaker output, and seamless integration with the provisioning ecosystem for company-wide ringtone deployment.

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

Why convert GSRT to MAUD?

GSRT only works on Grandstream IP phones. MAUD lets you use the audio outside the Grandstream ecosystem on standard devices.

What applications open MAUD files?

SOX and Amiga emulators can handle MAUD files. Most are available as free downloads for major operating systems.

How is the MAUD audio quality?

MAUD provides good quality at standard settings. The output clarity depends on the original GSRT recording quality.

How fast is the conversion?

Processing is fast — GSRT files are lightweight and MAUD encoding completes in seconds on our server hardware.

Are my files kept private?

GSRT uploads are removed right after processing. All MAUD output files are cleaned from servers within 24 hours.

Do I need to register?

No account required. Upload your file, convert, and download the result directly from your browser at convertio.tools.
