Figure 4.31. Device Options

The device options dialog lets you adjust the format of the recorded data. You can also select the devices for playback and midi output.


[Note] Note

These settings can only be changed on new files, before you have made any recording. The format of existing recordings cannot be changed. If you want to change these settings and they are disabled, click on FileNew first.

Sampling Rate

The Sampling Rate determines the number of measurements (samples) per second recorded from the input source. This is the same setting found on the Analyzer Settings dialog.

Sample Size

The sample size influences the quality but also the storage requirements of the recorded sound. The default setting of 16 bit per sample corresponds to the quality of standard audio CDs and should be sufficient for most purposes. A higher bit depth of 24 or 32 bit can be useful when the dynamic range of the recorded signal is very high, and when it contains very quiet passages that should later be amplified.

Channel Format

The channel format allows you to select between stereo and mono recordings. It is also possible to extract only the left or right channel of a stereo signal and save the resulting recording into a mono file. This can be useful with certain sound cards that do not properly support mono recordings, or if a stereo sound card has only one mono microphone connected to one of the channels. Note: A stereo recording requires twice as much storage space as a mono recording.

Temp Folder

This is the folder where Overtone Analyzer will store data as you are recording it. Make sure that you have enough hard drive space left. A mono recording with 44100 samples per second and a sample size of 16 bit requires about 350 MB (half a CD) per hour. The Temp Folder can only be set in the Live and Premium editions.


Wave Output Device

This is the device for playing back the recorded sound.

Midi Output Device

This is the device for playing the sounds from the piano keyboard and the overtones (except for the "Pure Sine Wave" overtone sound, which is played through the wave output device).
