Use one of \fBsrc-sinc-best-quality\f1, \fBsrc-sinc-medium-quality\f1, \fBsrc-sinc-fastest\f1, \fBsrc-zero-order-hold\f1, \fBsrc-linear\f1, \fBtrivial\f1, \fBspeex-float-N\f1, \fBspeex-fixed-N\f1, \fBffmpeg\f1, \fBsoxr-mq\f1, \fBsoxr-hq\f1, \fBsoxr-vhq\f1. See the documentation of libsamplerate and speex for explanations of the different src- and speex- methods, respectively. The method \fBtrivial\f1 is the most basic algorithm implemented. If you're tight on CPU consider using this. On the other hand it has the worst quality of them all. The Speex resamplers take an integer quality setting in the range 0..10 (bad...good). They exist in two flavours: \fBfixed\f1 and \fBfloat\f1. The former uses fixed point numbers, the latter relies on floating point numbers. On most desktop CPUs the float point resampler is a lot faster, and it also offers slightly better quality. The soxr-family methods are based on libsoxr, a resampler library from the SoX sound processing utility. The mq variant has the best performance of the three. The hq is more expensive and, according to SoX developers, is considered the best choice for audio of up to 16 bits per sample. The vhq variant has more precision than hq and is more suitable for larger samples. The Soxr resamplers generally offer better quality at less CPU compared to other resamplers, such as speex. The downside is that they can add a significant delay to the output (usually up to around 20 ms, in rare cases more). See the output of \fBdump-resample-methods\f1 for a complete list of all available resamplers. Defaults to \fBspeex-float-1\f1. The \fB--resample-method\f1 command line option takes precedence. Note that some modules overwrite or allow overwriting of the resampler to use. .TP +\fBavoid-resampling=\f1 If set, try to configure the device to avoid resampling. This only works on devices which support reconfiguring their rate, and when no other streams are already playing or capturing audio. The device will also not be configured to a rate less than the default and alternate sample rates. +.TP \fBenable-remixing=\f1 If disabled never upmix or downmix channels to different channel maps. Instead, do a simple name-based matching only. Defaults to \fByes.\f1 .TP +\fBremixing-use-all-sink-channels=\f1 If enabled, use all sink channels when remixing. Otherwise, remix to the minimal set of sink channels needed to reproduce all of the source channels. (This has no effect on LFE remixing.) Defaults to \fByes\f1. +.TP \fBenable-lfe-remixing=\f1 If disabled when upmixing or downmixing ignore LFE channels. When this option is disabled the output LFE channel will only get a signal when an input LFE channel is available as well. If no input LFE channel is available the output LFE channel will always be 0. If no output LFE channel is available the signal on the input LFE channel will be ignored. Defaults to \fBno\f1. .TP \fBlfe-crossover-freq=\f1 The crossover frequency (in Hz) for the LFE filter. Set it to 0 to disable the LFE filter. Defaults to 0. |
