Recording 25 tracks from Media Player into one mp3 file

I have asked this question before but have simplified my request by asking how do I record 25 tracks from my media files into just one track in mp3. I need this for our T.V. channel that uses MultiScreen and need to play continuous music throughout the day and the MultiScreen only accepts single tracks. Pykee 35

If it is CD tracks that you want in one file, please refer to the answers already given:

If you mean that they are files on your computer then you don’t need to record them. Use “File > Import > Audio” to import the files into Audacity.
When the files are imported, press Ctrl+A to select all the tracks, then use “Tracks > Align Tracks > Align End to End”.
If you need to adjust the position of the tracks, use the Time Shift tool.
Then use “File > Export” to create a new audio file.

If the files that you wish to use are not in a supported format you may still be able to use them if you install FFmpeg (see:

Audacity can’t Append-Import, where each time you import a new song it jams itself after the last one, all on one timeline. It’s a Feature Request, not a current tool.

If you have a lot of time, you can set up Audacity to record “What’s Playing On The Computer” and then make Media Player play all the songs one after the other. Audacity will collect them all on one timeline in real time. You don’t have to be there until the end to stop it and Export the MP3.

Can you Export an MP3? Have you actually done it to make sure it works right? Can you point to an MP3 that you made?


The down side of this process is you need to make darn sure the computer stays alive during the whole process and doesn’t wander off.

“Windows is doing a System Update. Please Wait.”
“Windows is entering Sleep Mode. Press the any key”


It is a feature request, but after selecting the multiple files and importing them into Audacity as multiple Audacity tracks, you can select tracks and use Tracks > Align Tracks > Align End to End which moves the tracks along the Timeline so the next one starts where the previous one finishes. Then you can Tracks > Mix and Render to make them into one Audacity track.

Files import into Audacity in alphanumerical order of their file names. So if tracks are not in the correct top to bottom order, you can click and drag on the Track Control Panel of tracks to move then up or down before the align and mix.
