02 / what you get
What happens to your data
Kept
- DTS surround files are supported
- Saved as Dolby Digital (AC3) at 448 kbps, the DVD standard, with stereo or 5.1 channels kept
- 5.1 surround is kept in the AC3
Good to know
- DTS files carry no title, artist or album tags, so there is nothing to copy over.
- The bitrate is fixed at 448 kbps even for stereo, so the file is about 3.4 MB per minute, far bigger than an MP3.
- AC3 only supports 32, 44.1 and 48 kHz, so other sample rates are converted.
- AC3 files cannot hold title, artist or album tags.
- Both formats compress with quality loss, so every conversion costs a little quality. Keep your DTS original.
