Digitising bell recordings
Abel uses digitised sound files in the standard Windows WAV format. One way you can make these is to use the Windows sound recorder. Alternatives are available commercially, or can be downloaded free from the internet (for example, Audacity).
Connect your tape recorder's "line out" socket to your PC's "line in" socket using a suitable cable, or connect your microphone to the PC's microphone socket.
Check the levels by playing one of your samples, or ringing the bell if recording directly to the PC. You may need to adjust recording levels or microphone placement if they are too high or too low.
Once the levels are right, you need to set the recording quality. For example, use "22,050Hz, 16 Bit, Mono". Abel sound samples should be mono, and any reasonable quality: 22KHz gives a tolerable trade-off between quality and file size.
Now play the bell sounds one at a time into the sound recorder, or ring the bells one at a time. After each one, save the resulting file with a name like "bell1.wav" in the directory C:\Program Files\Abel 3\Bells.
The bell sound must start immediately in your recorded samples, or there will be a delay between Abel ringing the bell and the bell sounding. If you have a sound editor you can use this to delete any such periods of silence.
You should also make sure that the total length of the sound sample is about 5 seconds; preferably, use a sound editor to fade the sound over that period. If you make it longer than this, the sound of many several bells ringing will be "muddy". If your sample isn't this long, you should pad it out with silence to 5 seconds or thereabouts (this is to avoid problems on some computers with bells occasionally failing to sound. See Troubleshooting for more information about this problem and how to deal with it, if it happens to you).
