Export/Import data to/from external file

Hallow Forum,
I use version audacity 2.3.2. on Windows 10.
I exported data via “Gereedschap/Sample-data exporteren” in file sample-data.txt.
Then closing the current audacity-file.
Then importing the data from sample-data.txt via “Gereedschap/sample-data importeren” in a new file.

In the new-file is only one line from the stereo-signal present.
And the sound of the previous music is fully distorted.
There is no noise from the original sound.
What has happened.
I hope you can help me.
Hi, Jan Ra.

If you are importing stereo data, you need to create a stereo track first. (Tracks > Add New > Stereo Track).

As with Audacity’s “Generators”, if the effect is run without a track selected, it will create a mono (1 audio channel) track.

The other settings that you need are listed in the manual: https://manual.audacityteam.org/man/sample_data_import.html#Obtain_data_from_.27Sample_Data_Export.27
