Converting 44.1 kHz Sample-Rate Loops to 22.5 kHz Sample Rate

By now you should have a number of loops that you have worked up using a click track. Also you have added or included at least 50 ms (milliseconds) of the loop's audio track before and after the part of the audio that you want to loop. Again' if you did not read the previous CoffeeBreak you're going to be in trouble.

If you've come this far with us you're probably familiar with your specific digital audio program by now. Go ahead and take all of your loops and convert the sample rate to 16 bit, 22.5 kHz. Export them into a common folder entitled "remixaudio," or something else easy to remember. If you're using Digital Performer, go into the "soundbites" window and go through the "sample rate conversion" menu to export the files as AIFF, WAV, or Sound Designer II files. You can export them as any file type you want, as a matter of fact, because the Beatnik Editor Pro will take any of the three (AIFF, WAV, SDII), as well as .au and a few others.

If you're not familiar with how to convert sample rates with your digital audio/MIDI sequencing program you have to be able to at least export your sound file loops into a common folder then follow the tutorial below on how to use BarbaBatch to do so. If you are using a PC, you can download a program out of the Angry Coffee Toolbox below and take the tutorial on how to use it. You should be able to translate it to any other audio editing tool...

The following is the BarbaBatch tutorial on how to make a custom patch for the program to convert CD quality audio to the format needed for the Beatnik Editor Pro work that is coming up (16 bit 22.5khz). If you already know how to do this, skip along to the Getting Organized! Map It All Out Section.

1. Download the free BarbaBatch demo or pay for the $99 full version and follow the installation instructions.
2. Click on the Input button, so you can import your CD-quality (hopefully) sound file into the sound editing program by clicking the Add button.
3. Go to the correct folder on your computer, find your sound file, and highlight it and click yet another Add button. This window has much more, too: you can see the current sample rate and length of the sound file as well as the capability to audition or play the file.
4. Click on the Conversion button, and you can add a template, or command a preset to simply edit the sound file and convert its sample rate to 16 bit 22.5 kHz. The program has nine presets you can use as examples of ways to utilize this type of tool works. Many of the options in this affordable product are geared toward Internet use.
5. The program should now ask you to Define New Conversion. For this example, we told the program to convert the file to another specific file type (in this case a .wav file ), convert the sample rate to 22.5 kHz, convert to a different bite rate -- 16 bits -- Now click the Add button. After you get the hang of it, you can use some of the other options if need, or if you're just curious.
6. Click the Output button, choose your destination file folder and click the cute bow-and-musical-arrow Start button.
