Why should I convert SD2 audio to MP3?

SD2 is an uncompressed format used in legacy Mac audio software, making files huge and difficult to share. MP3 compresses audio to a fraction of the size while remaining compatible with modern devices, operating systems, and streaming services. Converting SD2 to MP3 ensures your audio can be played anywhere, and reduces storage requirements for large libraries.

What happens to audio quality and metadata when converting SD2 to MP3?

Our converter decodes SD2's PCM data and re-encodes it using the MP3 codec at the bitrate you select. The sample rate and channel count are preserved, and ID3 tags (like title and artist) are copied automatically. However, MP3 is lossy: audio frequencies above the bitrate-dependent cutoff are permanently removed. Use a higher bitrate (e.g., 320kbps) to minimize audible differences.
