The plugin in rate subdirectory is an external rate converter using
|
|
Packit |

libsamplerate by Erik de Castro Lopo. You can use this rate converter
|
|
Packit |
675970 |
plugin by defining a rate PCM with "converter" parameter, such as:
|
|
Packit |
675970 |
|
|
Packit |
675970 |
pcm.my_rate {
|
|
Packit |
675970 |
type rate
|
|
Packit |
675970 |
slave.pcm "hw"
|
|
Packit |
675970 |
converter "samplerate"
|
|
Packit |
675970 |
}
|
|
Packit |
675970 |
|
|

The plug plugin has also a similar field, "rate_converter".
|
|
Packit |
675970 |
|
|
Packit |
675970 |
Or, more easily, define a global variable "defaults.pcm.rate_converter",
|
|
Packit |
675970 |
which is used as the default converter type by plug and rate plugins:
|
|
Packit |
675970 |
|
|
Packit |
675970 |
defaults.pcm.rate_converter "samplerate"
|
|
Packit |
675970 |
|
|
Packit |
675970 |
Write the above in your ~/.asoundrc or /etc/asound.conf.
