Command line audio player: QoaPlay 0.7 (update)
The relatively new "Quite OK Audio Format" (QOA) is a lossy audio compression format: audio signals (44100hz, stereo) are encoded at 278 kbits/s, exactly 1/5 of the bits required for an uncompressed WAV file. Following on from the QoaToAiff decoder (amiga-news.de reported), Grzegorz Kraszewski has now released a player called QoaPlay (source code on Codeberg) for the Amiga 40 Tools Jam 2025.
According to the developer, the following hardware requirements should be met for real-time playback:
- 68030@25 for Stereo 44,1 kHz.
- 68020@25 for Stereo 22,05 kHz oder Mono 44,1 kHz.
- 68020@14 or 68000@33 for Mono 22,05 kHz.
Currently, QoaPlay uses audio.device for 8-bit playback and does not check the maximum sample rate. This can result in distortion, for example, when playing a 44.1 kHz file on an Amiga in PAL mode. Automatic halving of the sample rate will be implemented later. A 16-bit AHI output mode is planned.
Update: (04:33, 08.10.25, dr)
Version 0.7 is now available: QoaPlay now performs the announced automatic halving of the sampling rate if the QOA file has a sampling rate above 27 kHz.eist. (dr)
