soundtouch-2.3.0

[Bruce Dubbs]

New minor version.

[Douglas R. Reno]

Promote back to 11.0.

[Bruce Dubbs]

2.3.0:

• Disable setting "SOUNDTOUCH_ALLOW_NONEXACT_SIMD_OPTIMIZATION" by default. The original purpose of this setting was to avoid performance penalty due to unaligned SIMD memory accesses in old CPUs, but that is not any more issue in concurrent CPU SIMD implementations and having this setting enabled can cause slight compromise in result quality.

• Bugfix: soundtouch.clear() to really clear whole processing pipeline state. Earlier individual variables were left uncleared, which caused slightly different result if the same audio stream were processed again after calling clear().

• Bugfix: TDstretch to align initial offset position to be in middle of correlation search window. This ensures that with zero tempo change the output will be same as input.

• Bugfix: Fix a bug in TDstrectch with too small initial skipFract value that occurred with certain processing parameter settings: Replace assert with assignment that corrects the situation.

• Remove OpenMP "_init_threading" workaround from Android build as it's not needed with concurrent Android SDKs any more.
