Sampling Parameters

SU700 samples are characterized by three parameters: sampling frequency, bit reso- lution, and format (stereo or monaural). If you are recording a sample from an analog source, you can set values for each of these parameters. If you are recording a digital signal, the values are fixed at time of recording (in accordance with the source signal) but can be changed later using the SAMPLE PROCESS jobs (→ p.262).

Sampling Frequency

The rate at which digital readings are taken is referred to as the sampling rate or sampling frequency. A conventional audio CD uses a sampling frequency of 44.1kHz (44,100 readings per second). The SU700 supports frequencies of 44.1, 22.05, and 11.025 kHz frequencies. Note that higher frequencies produce higher-fidelity sound reproduction, but also consume a greater quantity of sampling memory.

Bit Resolution

The precision of each reading is restricted by the number of bits used to record the value. A conventional audio CD uses 16 bits to store each value. The SU700 allows you to choose a resolution of either 16 bits or 8 bits. Again, the higher resolution provides higher-fidelity recording, while the lower resolution cuts memory con- sumption in half.

Stereo/Mono

The SU700 supports both stereo and monaural samples.

Sample Editing

You can use the various SAMPLE jobs to edit the samples that have recorded or imported into the SU700. Editing capabilities are outlined below; for more detailed in- formation, refer to the indicated pages.
