Your device and sample rate selections appear at the top of the Audio Settings Popover.
Choosing a sample rate is important as it dictates your ability to capture certain frequencies. For most audio measurements, 44100Hz is sufficient as it easily captures up to 20kHz. Far more spectral content than is required for most acoustics tasks.
In general, dividing the sample rate by two gives you the theoretical upper bound of frequencies you are able to capture. Further reading on the Sampling Theorem or the operation of DACs and ADCs is recommended if you wish to understand this further.
The Sample Rate PopUp contains a list of sample rates that both the Playback and Record Devices have in common.
New in 4.0: Using a fixed rate between both the Playback and Record devices is less error-prone than allowing for mixed measurements, so it is the default mode of operation in FuzzMeasure 4. |
These PopUp controls allow you to select your Playback and Record devices, respectively. Changing your playback and/or record device will cause the Sample Rate PopUp to reload in case the previously-selected sample rate is no longer common to both devices.
