Re: 24 bits truncated to 16 bits...

In my processing pipeline, I save an Audacity project for the source and a separate project for the processed result. The idea is, to record the LP once in as good a representation that can be created and store it away ("one and done"); then export a WAV file to start the processing pipeline, proecs...

Re: 24 bits truncated to 16 bits...

The WAV files are too big to upload. I've attached the start of the hex dumps. The files record the same track but don't start *precisely* at the same point. There does appear to be a repeating pattern of 0's every third byte when dithering is shut off (KJSNDhead.txt). So ... in this situation, woul...

Re: 24 bits truncated to 16 bits...

I'll run another experiment to ensure what options are in effect for the recording I upload.

But should I be changing the dither for "real time conversion" or "high quality conversion"?

Re: 24 bits truncated to 16 bits...

The following is the start of a WAV file hex dump. 1. Recorded by Audacity as 24-bit on Windows 7. 2. Exported as 24-bit WAV without additional processing 3. I'm not sure I see the pattern of zeroes that would indicate that the recording actually has 16-bit samples. 4. Help? 0000000 4952 4646 6dfc 0...

Re: 24 bits truncated to 16 bits...

Thanks. I generally record in 32-bit float @ 96KHz and export as 24-bit WAV.

Re: 24 bits truncated to 16 bits...

Can you clarify whether the bits are lost on input recording or on file export from Audacity? I use Audacity on Windows 7, recording with a Roland UA-1EX USB sound capture device.

Re: recording a vinyl album at one setting

When the resulting files are played in order, the exact placement of the splits between tracks doesn't matter. (Particularly if you are seeking to recreate the experience of playing the album, including the sound of the needle in between tracks.) However, the splits do become an issue when you intro...
