Rate Converter Plugin Using Libsamplerate
|
|
=========================================
|
|
|
|
The plugin in rate subdirectory is an external rate converter using
|
|
libsamplerate by Erik de Castro Lopo. You can use this rate converter
|
|
plugin by defining a rate PCM with "converter" parameter, such as:
|
|
|
|
pcm.my_rate {
|
|
type rate
|
|
slave.pcm "hw"
|
|
converter "samplerate"
|
|
}
|
|
|
|
The plug plugin has also a similar field, "rate_converter".
|
|
|
|
Or, more easily, define a global variable "defaults.pcm.rate_converter",
|
|
which is used as the default converter type by plug and rate plugins:
|
|
|
|
defaults.pcm.rate_converter "samplerate"
|
|
|
|
Write the above in your ~/.asoundrc or /etc/asound.conf.
|
|
|
|
The following converter types are available:
|
|
|
|
- samplerate_best Use SRC_SINC_BEST_QUALITY
|
|
- samplerate_medium Use SRC_SINC_MEDIUM_QUALITY
|
|
- samplerate Use SRC_SINC_FASTEST
|
|
- samplerate_order Use SRC_ZERO_ORDER_HOLD
|
|
- samplerate_linear Use SRC_LINEAR
