Frequently Asked Questions
What is PCM format?
PCM (Pulse Code Modulation) is the standard uncompressed digital audio format used in WAV files, CDs, and most digital audio systems. It stores audio as discrete samples at regular intervals. PCM can store multi-channel surround sound.
Should I choose Stereo or Original channels?
Choose Stereo for standard playback on headphones, phones, or stereo systems - the 5.1/7.1 surround will be intelligently downmixed. Choose Original to preserve the full multi-channel surround sound for home theater systems, archiving, or professional work.
Should I choose 16-bit or 24-bit?
24-bit provides greater dynamic range (144 dB vs 96 dB) and is ideal for professional work, archiving, or further processing. 16-bit is CD quality and sufficient for final listening copies. For surround sound archiving, 24-bit is recommended.
How large will the PCM files be?
PCM WAV files are uncompressed and very large. A 3-minute stereo track at 16-bit will be about 30 MB. At 24-bit, it's ~50 MB. For 5.1 surround, multiply by 3. For 7.1 surround, multiply by 4. Much larger than compressed formats but preserves full quality.
What's the difference between DTS-to-PCM and DTS-to-WAV?
They are essentially the same - PCM is the encoding method, and WAV is the container format. Both produce uncompressed WAV files with PCM audio data. The tools offer identical functionality with the same quality settings.
