snd_pcm_plugin_set_src_method()

Set the system's source filter method (plugin-aware)

Synopsis:

#include <sys/asoundlib.h>

unsigned int snd_pcm_plugin_set_src_method (
                snd_pcm_t *handle,
                unsigned int method );

Arguments:

handle

The handle for the PCM device, which you must have opened by calling snd_pcm_open() or snd_pcm_open_preferred().

method

The filter that you want to use:

• 0 — basic linear interpolated SRC (the default)
• 1 — basic anti-aliased SRC filter (7-point Kaiser windowed)

Library:

libasound.so

Description:

The snd_pcm_plugin_set_src_method() function sets the source filter method. If you want to set this method, do so before you call snd_pcm_plugin_params(), so that the plugin can be properly initialized (including the filters).

Returns:

The current method.

Classification:

QNX Neutrino

Caveats:

Make sure that you don't mix and match plugin- and nonplugin-aware functions in your application, or you may get undefined behavior and misleading results.
