Chapter 5 Samples and Sampling 151

CHAPTER 5

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 ana-

log 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 im-

ported into the SU700. Editing capabilities are outlined below; for more detailed in-

formation, refer to the indicated pages.
