New Feature Request - Export of 36 Channel File

Audacity 3 Help Forum
1

[Updated with corrections]

I have a 36-channel w64 file created with another DAW program.

If I read the 36-channel file into Audacity and select a portion of it (for example the first 8 seconds), I can’t export more than 32 channels.

Here’s what I’m doing after I read in the 32-channel file:

I select the region I want on all 36 channels.

I do File → Export Audio → Export to computer → Custom Mapping with Current Selection

(It’s a 96000 Hz Sample Rate / Signed 24-bit PCM Encoding file.)

When I do “Configure” for the Custom Mapping, it only shows 32 output channels. I can’t get 36.

Can anyone advise, please? Or would the development team please consider expanding the Export Audio to more than 32 channels?

What is a “w64”-file?

We’re recording audio that uses much larger files than WAV can handle in a single file.

A WAV file is limited in size to 4 GB.

W64 allows much, much larger file sizes. Most DAWs (including Audacity) support it.

From the manual:

When you click on the Configure button in the Export Audio dialog, this dialog appears which presents you with the number of tracks you have in your project and allows you to map these as desired to each of up to

I was mistaken: Export Audio only allows us to export to a 32-channel .w64 file under all conditions.

Perhaps Export Audio’s number of channels could be expanded to at least 36 channels for all situations?

I think w64 format can support an arbitrary number of channels, so why not 37 channels, or 45, or 128, or 30000000?

Indeed.

We have an application that needs 36. But Audacity currently limits it to 32.
