./audio/soundtouch, Library for changing the tempo, pitch, and playback rates of audio

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.3.1, Package name: soundtouch-2.3.1, Maintainer: pkgsrc-users

SoundTouch is an open-source audio processing library for changing
the Tempo, Pitch and Playback Rates of audio streams or audio files

Tempo (time stretch): Changes the sound to play at faster or
slower tempo than originally without affecting the sound pitch.

Pitch (key): Changes the sound pitch or key while keeping the
original tempo (speed).

Playback Rate: Changes both tempo and pitch together as if a
vinyl disc was played at different RPM rate.

The SoundTouch library is intended for application developers
writing sound processing tools that require tempo/pitch control
functionality, or just for playing around with the sound effects.

*: remove pkg-config from tools where no buildlink3.mk file is included

Bulk build on NetBSD of these packages had the same result as before
(build succeeds, no PLIST change).

Log message:
soundtouch: update to 2.3.1


     * Adjusted cmake build settings and header files that cmake installs


       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.


     * Improved source codes so that compiler can autovectorize them more
       effectively. This brings remarkable improvement e.g. ARM cpus equipped
       with NEON vfpu: Bencmarked 2.4x improvement in execution speed in
       ARMv7l vs the previous SoundTouch version for both integer and
       floating point sample types.
     * Bugfix: Resolved bad sound quality when using integer sample types in
       non-x86 CPU
     * Bugfix: Fixed possible reading past end of array in BPM peak detection

all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
soundtouch: updated to 2.1.2

Bugfixes: Fixed potential buffer overwrite bugs in WavFile routines. Replaced \ 
asserts with runtime exceptions.
Android: Migrated the SoundTouch Android example to new Android Studio
Automake: unset ACLOCAL in bootstrap script in case earlier build script has set it

Refactored C# interface example
Disable anti-alias filter when switch SOUNDTOUCH_PREVENT_CLICK_AT_RATE_CROSSOVER \ 
defined because anti-alias filter cause slight click if the rate change crosses \ 
zero during processing
Added script for building SoundTouchDll dynamic-link-library for GNU platforms
Rewrote Beats-per-Minute analysis algorithm for more reliable BPM detection
Added BPM functions to SoundTouchDll API
Migrated Visual Studio project files to MSVC 201x format
Replaced function parameter value asserts with runtime exceptions
Code maintenance & style cleanup

Added functions to get initial processing latency, duration ratio between the \ 
original input and processed output tracks, and clarified reporting of \ 
input/output batch sizes
Fixed issue that added brief sequence of silence to beginning of output audio
Adjusted algorithm parameters to reduce reverberating effect at tempo slowdown
Bugfix: Fixed a glitch that could cause negative array indexing in quick seek \ 
Bugfix: flush() didn't properly flush final samples from the pipeline on 2nd \ 
time in case that soundtouch object instance was recycled and used for \ 
processing a second audio stream.
Bugfix: Pi value had incorrect 9th/10th decimals
Added C# example application that uses SoundTouch dll library for processing MP3 \ 

Fix in GNU package configuration

Improved SoundTouch::flush() function so that it returns precisely the desired \ 
amount of samples for exact output duration control
Redesigned quickseek algorithm for improved sound quality when using the \ 
quickseek mode. The new quickseek algorithm can find 99% as good results as the \ 
default full-scan mode, while the quickseek algorithm is remarkable less CPU \ 
Added adaptive integer divider scaling for improved sound quality when using \ 
integer processing algorithm
