How do I convert FLAC to SD2 step by step?

Upload your FLAC file to the converter, choose SD2 as the output format, and select your preferred sample rate and bit depth (e.g., 44.1 kHz / 16-bit). Click 'Convert' and wait for the process to finish. Then download the SD2 file and import it into Pro Tools or any SD2-compatible application. No audio quality is lost during the conversion.

Why would I convert FLAC to SD2 instead of keeping the original FLAC?

FLAC is a lossless compressed format that many modern players support, but some professional audio workstations and legacy hardware—especially older Pro Tools systems—require or work best with SD2. SD2 stores uncompressed PCM audio and includes timestamp and region markers, making it the preferred format for archival or studio compatibility when working with such tools.

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

Since FLAC is lossless and SD2 stores uncompressed PCM, the audio data (sample rate, bit depth, and waveform) is preserved bit-for-bit. The main change is file size: SD2 files are larger because they are uncompressed. Metadata such as timestamp information is retained, and SD2's region markers are written where applicable, but compression-specific markers from FLAC are not needed.

Yes, FLAC-TO-SD2 on LetsConvert is 100% free with no registration or hidden fees required.
