Notes

1. Instead of Audioactive Production Studio you can also use dBpowerAMP Music Converter (db). Click to Download
Click here for their DBpowerAMP - wma and other codexs are freely available from them.

2.
For converting a wav file to an mp3 using non-studio software, like db, you will also have to
Click to Download the LAME codecs.

3. If the sound is too soft, you will need to use a function called normalise which brings the sound waves up to maximum - this option is available with db.

4. When recording, it's best to choose mono - this is not only to save space, but balance is achieved when recordings are poor. Otherwise the right channel could be loud and the left soft, making it uncomfortable to listen to.

5. When recording, don't stop the pc recorder while changing sides. Carry on recording until the tape comes to the end. Then examine the sound waves - a large blank space appears where you changed side. Highlight this area and press delete. This will neatly join side 1 with side 2.

6. Sound levels - keep the Microphone volume on Volume Control low, and boost the incoming signal by increasing the volume on your hi-fi set. This will reduce the background noise levels. A setting between 25 and 40% is best.

7. Using the above settings shown in the diagram, results in mp3 filesizes of 6 to 12mb depending on talk length. This means you can fit about 70 talks on a single computer cd.
