Export bug?

[shadowinthelight]

I use Exact Audio Copy to rip CDs and remove the silence at the beginning and end of tracks before converting to MP3.



I noticed even if I make no edits to the wave file and only open and export it back to wave in Audacity 1.3.12 the zero samples are no longer zero making EAC unable to delete what was silence.



Is this a bug or am I making a n00b mistake and missing a setting somewhere to prevent this alteration?

If you use Audacity's default settings which include importing files at 32-bit resolution ("Default Sample Format" in Quality Preferences) and then export to 16-bit WAV, Audacity will apply low level Dither Noise to smother clicky noise which could arise from downsampling from 32-bit to 16-bit. That isn't a bug, but even if you changed the Quality setting to 16-bit resolution and exported a 16-bit WAV, Audacity would needlessly apply dither. That is a known bug.

You can turn off dither when writing data (for example when exporting) at "High-quality Conversion" in the Quality Preferences. Preferences are at the bottom of the Edit menu.

I saw those setting and can't believe I didn't make the mental connection. Maybe I should stop doing this sort of thing late at night. Thank you.
