Free online SPC to FLAC converter

Some audio players and editing or archiving workflows accept FLAC but not SPC game-music files. Converting an SPC recording to FLAC renders its playback as a standard audio track that can be played and edited in those programs.

What the SPC format is

SPC files store a snapshot of the Super Nintendo Entertainment System’s SPC700 sound processor and memory, along with optional track metadata. They are used to preserve and play music from SNES games, and commonly come from emulator dumps or SPC ripping tools. Playback requires software that emulates the console’s audio hardware.

What the FLAC format is

FLAC stores digital audio using lossless compression. It is suitable for playback, editing, and archiving in software that supports standard audio files; unlike SPC, it contains rendered sound rather than console playback data.

How to convert SPC to FLAC

Online on 101convert.com

1. Upload one or more SPC files on the 101convert.com converter page; batch conversion is available, subject to the per-file size limit shown there.
2. Choose FLAC and, if needed, set the sample rate and channel count before converting. The conversion runs on the server with FFmpeg.
3. Start the conversion and download the resulting FLAC file or files.

Offline with desktop software

foobar2000 is a free option for Windows. Install foobar2000 and its Game Emu Player component, which adds SPC playback, then open the SPC file. Select the track, choose Convert → …, set the output format to FLAC, and start conversion. If FLAC is not listed, configure a FLAC encoder in foobar2000’s converter settings.

Quality and limitations

FLAC preserves the rendered audio losslessly, but the conversion does not preserve the SPC data or make the process lossless relative to the original game soundtrack. The player emulates the SPC700 to create audio; the chosen sample rate and channel count affect the rendered output. Some SPC files include track-length and fade metadata; without usable length information, playback may loop or be cut off according to the player’s duration settings. Check the output’s ending and duration.
