Different sampling frequency mixing algorithm

It is not possible to perform channel mixing by a different sampling frequency group.

Note that when channel synthesis is performed on a sampling frequency group other than the selected sampling frequency

group, playback will be faster or slower.

The following table lists the frequency group that can be used when mixing different sampling frequency groups.

6.4kHz, 12.8kHz, 25.6kHz

... (Group 1)

8.0kHz, 16.0kHz, 32.0kHz

... (Group 2)

11.025kHz, 22.05kHz, 44.1kHz

... (Group 3)

12.0kHz, 24.0kHz, 48.0kHz

... (Group 4)

10.7kHz, 21.3kHz

... (Group 5)

The figure below shows the operation image when a sampling frequency group with different sampling frequency group is

played back.

Figure 1) Case where a phrase is played at a sampling frequency belonging to a different

sampling frequency group during playback on channels 1 and 2

Figure 2) Case where a phrase is played at a sampling frequency belonging to a different

sampling frequency group after playback is finished at the other channel

Channel 1

Channel 2

Playback at

fs=16.0kHz

Playback at fs = 25.6kHz

Channel 1

Channel 2

Playback at

fs=16.0kHz

Switch to playback at fs=12.8kHz.
