Setting the Audio Source Audio should be captured at the highest possible quality. If the level cannot be accessed within the application, it must be adjusted from the desktop. Note that audio sources have different stages in the input and output chains that may vary in gain level. Examine every point in the audio chain to ensure that the volume level at all locations is equal. Experiment with these to determine which ones provide the best gain without distortion.
Decisions regarding audio compression, bit size, and sampling frequency, are necessary.
Typically, the highest quality possible is with a 22.05 kHz sampling frequency. Some applications provide the ability to capture using a 44.1 kHz sampling frequency. A digital sound editor may be used to remove unwanted noises or to alter the sound content after capture. If disk space is available, use a sixteen bit sample size. This is the size currently used in CD players, and provides the cleanest, most accurate sound reproduction.
