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

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


Branch: CURRENT, Version: 2.1.2, Package name: soundtouch-2.1.2, 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.

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

2.1.1:
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

2.1:
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

2.0:
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 \ 
algorithm
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 \ 
files

1.9.2:
Fix in GNU package configuration

1.9.1:
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 \ 
intensive.
Added adaptive integer divider scaling for improved sound quality when using \ 
integer processing algorithm

Log message:
update to soundtouch-1.9.0
from README.html:
1.9:

    Added support for parallel computation support via OpenMP primitives for
    better performance in multicore systems. Benchmarks show that achieved
    parallel processing speedup improvement typically range from +30% (x86
    dual-core) to +180% (ARM quad-core). The OpenMP optimizations are disabled
    by default, see OpenMP notes above in this readme file how to enabled these
    optimizations.

    Android: Added support for Android devices featuring X86 and MIPS CPUs, in
    addition to ARM CPUs.

    Android: More versatile Android example application that processes WAV audio
    files with SoundTouch library

    Replaced Windows-like 'BOOL' types with native 'bool'

    Changed documentation token to "dist_doc_DATA" in Makefile.am file

    Miscellaneous small fixes and improvements
