[Bug 1494155] Re: [mako] pulseaudio resample methos missing src-sinc-*

 

Hi,

Upstream has decided to phase out libsamplerate, as speex gives better
"bang for the buck", i e better audio quality for the same CPU or same
quality for less CPU.

Ubuntu Touch is apparently ahead of schedule - but expect the distro to
stop supporting these in the future:

src-sinc-best-quality
src-sinc-medium-quality
src-sinc-fastest
src-zero-order-hold
src-linear

** Changed in: pulseaudio (Ubuntu)
       Status: New => Won't Fix

Title:
  [mako] pulseaudio resample methos missing src-sinc-*

Status in pulseaudio package in Ubuntu:
  Won't Fix

Bug description:
  I tried to change the pulse resampling on my mako to src-sinc-best-
  quality and medium, to no avail.

  Later i found out that the pulse shipped with mako isnt capable of
  using these resampling methods.

  $ pulseaudio --dump-resample-methods
  trivial
  speex-float-0
  speex-float-1
  speex-float-2
  speex-float-3
  speex-float-4
  speex-float-5
  speex-float-6
  speex-float-7
  speex-float-8
  speex-float-9
  speex-float-10
  speex-fixed-0
  speex-fixed-1
  speex-fixed-2
  speex-fixed-3
  speex-fixed-4
  speex-fixed-5
  speex-fixed-6
  speex-fixed-7
  speex-fixed-8
  speex-fixed-9
  speex-fixed-10
  ffmpeg
  auto
  copy
  peaks

  while on an other system (non ubuntu touch) i get the correct
  resampling methods:

  $ pulseaudio --dump-resample-methods
  src-sinc-best-quality
  src-sinc-medium-quality
  src-sinc-fastest
  src-zero-order-hold
  src-linear
  trivial
  speex-float-0
  speex-float-1
  speex-float-2
  speex-float-3
  speex-float-4
  speex-float-5
  speex-float-6
  speex-float-7
  speex-float-8
  speex-float-9
  speex-float-10
  speex-fixed-0
  speex-fixed-1
  speex-fixed-2
  speex-fixed-3
  speex-fixed-4
  speex-fixed-5
  speex-fixed-6
  speex-fixed-7
  speex-fixed-8
  speex-fixed-9
  speex-fixed-10
  ffmpeg
  auto
