Free online PSM to FLAC converter

Source format: PSM

PSM is a tracker music module format associated with ProTracker Studio and related music tools. It stores song data as patterns, instruments, and playback instructions rather than as recorded audio. Because of that, PSM files are typically small and are used for game music, demos, and retro-style compositions. To listen to a PSM file on modern devices, it usually needs to be rendered or converted into a standard audio format.

Target format: FLAC

FLAC stands for Free Lossless Audio Codec. It is a compressed audio format that preserves the original audio data without quality loss. FLAC is widely supported by music players, audio editors, and archival workflows. It is a good choice when you want high-quality, lossless audio with smaller file sizes than WAV, while keeping the ability to edit or archive the result.

How to perform the conversion

Because PSM is a tracker module format, the conversion must first render the module to audio. The best approach is to use software that can open PSM files and export or record them as FLAC.

1. Open the PSM file in compatible tracker software. A practical option is OpenMPT, which can load many module formats and is often used for playback and conversion.
2. Verify playback. Play the song to make sure instruments, tempo, and effects are interpreted correctly before exporting.
3. Export or render to audio. In OpenMPT, use File → Export → Audio or a similar export option, then choose a lossless output if available. If the program exports WAV only, export to WAV first and convert that WAV to FLAC in the next step.
4. Convert WAV to FLAC if needed. If your tracker software does not export FLAC directly, use a dedicated audio converter such as ffmpeg or flac. For example, with ffmpeg you can run ffmpeg -i input.wav output.flac.
5. Check the result. Open the FLAC file in a media player to confirm that the duration and sound match the original module playback.

If you prefer a simple browser-based workflow, you can convert the file on 101convert.com for free without installing any software, provided the site supports this specific input and output combination.

Notes on quality and limitations

PSM to FLAC is not a direct format-to-format transcode in the usual sense, because PSM is not recorded audio. The module must be played back and rendered, so the final FLAC depends on the player’s synthesis engine, sample handling, and effect interpretation. This means different software may produce slightly different results.

For best quality, use a player or tracker that is known to handle PSM files accurately, export at a high sample rate such as 44.1 kHz or 48 kHz, and avoid unnecessary resampling. FLAC is lossless, but it can only preserve the quality of the rendered audio; it cannot recover details that were not produced during playback. If the PSM file uses unusual instruments or relies on a specific tracker implementation, compatibility may vary.
