- Rate Converter Plugin Using Speex Resampler
- ===========================================
-
- The plugin in rate subdirectory is an external rate converter using
- the Speex resampler (aka Public Parrot Hack) by Jean-Marc Valin. 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 "speexrate"
- }
-
- 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 "speexrate"
-
- Write the above in your ~/.asoundrc or /etc/asound.conf.
-
- The following converter types are available:
-
- - speexrate_best Use quality 10 (equivalent to SRC_SINC_BEST_QUALITY)
- - speexrate_medium Use quality 5 (equivalent to SRC_SINC_MEDIUM_QUALITY)
- - speexrate Use quality 3 (equivalent to SRC_SINC_FASTEST)
