Export to PCM 8bit Mono 8khz

Have been unable to create a WAV file with the following export specs: PCM, 8bit, Mono, 8khz.
Have read all of the posts on this topic, tried them, none seem to work.

Using Windows 7 Ultimate, 64-bit, SP1.
Audacity 2.03, downloaded using exe module on 09-13-13.

Have recorded a brief voice message using USB headset, mono mode. Must be exported to above specs in order to upload into a medical records system.

Tried a variety of export settings - what is suggested the most is Project Rate of 8000, export as “other compressed file”, options of Header = WAV (Microsoft) and Encoding = Unsigned 8-bit PCM. That yields a file of 1 min. 16 sec. in length, bit rate of 64kbps.

The upload of this file is rejected by the medical records system. The reason given by the tech support of that system is that the file format is wrong.

Help in achieving this goal would be greatly appreciated.

The reason given by the tech support of that system is that the file format is wrong.

Did they give you a suggestion of exactly how they produce sound files for the system?

Just because we’ve been ensnarled in conflicts before, are you trying to circumvent the company’s own expensive, proprietary file creation system?


Your settings are correct. Your system may want WAVEX header, so try that. Don’t add any metadata to the file.

Otherwise, attach a file a few seconds long that is in a format your records system accepts. Please see here for how to attach files: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1 .


No indeed, not circumventing anything. Tech Support’s directions for creating the file are to use the Sound Recorder in Windows XP, and that is not available in Windows 7, which is what we are using.

I will try the WAVEX suggestion.

Will have to ask Tech Support for a working file to attach, as this is the first time we have attempted to create and upload a message file.

Thank you for the responses.

is not available in Windows 7

How sure are you of that? Is one of the problems that your computer or motherboard has no analog soundcard?


We use Sound Recorder frequently for testing. Win7 does like to “hide things” it thinks you won’t need. I know I’m talking you out of business, but it would be good to know how to configure Audacity to do this as well as getting Sound Recorder working. This is a conversation, not a help desk.


Yep, sound card present. Windows 7 Sound Recorder works; creates a wma file.

Agreed, it would be good to know how to configure Audacity to record and export the wav file matching the specs. Will keep plugging.

creates a wma file.

That’s not what the other company wants, is it? Windows Media is not 8-bit PCM, etc, etc. It’s m4a or mpeg4, I forget.

Will keep plugging.

Thank you.


WMA formats are lossy (apart from WMA lossless) but are not part of the MPEG standard.

For what it’s worth, you can copy the XP Souund Recorder (sndrec32.exe) from an XP machine onto a Windows 7 machine (even 64-bit) and it will work.
