Convert SD2 to 669

Understanding SD2 and 669 file formats

SD2 (Sound Designer II) is an audio file format developed by Digidesign, primarily used on Macintosh systems for professional audio editing and recording. It supports high-quality, uncompressed audio and was widely used in the music and post-production industries.

669 is a module file format used for storing music created with trackers, specifically the Composer 669 and Unis 669 trackers. Unlike SD2, 669 files contain both audio samples and sequencing data, allowing for playback of multi-channel music on compatible software.

Why convert SD2 to 669?

Converting from SD2 to 669 is uncommon, as these formats serve different purposes: SD2 is for raw audio, while 669 is for tracker-based music. However, if you wish to use SD2 audio samples in a tracker environment, converting and importing them into a 669 module can be useful for music production or retro game development.

How to convert SD2 to 669

Direct conversion from SD2 to 669 is not straightforward due to the fundamental differences between the formats. The process typically involves two steps:

1. Convert SD2 to WAV: Use an audio converter to change the SD2 file into a more widely supported format like WAV.
2. Import WAV into a tracker: Use a tracker program that supports 669 files (such as OpenMPT or Schism Tracker) to import the WAV sample and create a 669 module.

Recommended software for conversion

• Audacity: Free, cross-platform audio editor that can open SD2 files and export them as WAV. Use File → Export → Export as WAV.
• OpenMPT: A modern tracker for Windows that can import WAV samples and save modules in the 669 format. Use File → New to create a 669 module, then Instrument → Import Sample to add your WAV file, and finally File → Save As to export as 669.
• Schism Tracker: A cross-platform tracker that supports 669 files and sample import.

Step-by-step conversion process

1. Open your SD2 file in Audacity.
2. Export the audio as WAV using File → Export → Export as WAV.
3. Open OpenMPT or Schism Tracker and create a new 669 module.
4. Import the WAV file as a sample.
5. Arrange your samples and patterns as desired.
6. Save the project as a 669 file using File → Save As.

Conclusion

While there is no direct SD2 to 669 converter, using audio editors and tracker software allows you to bring SD2 audio into the 669 module format for creative music production.
