Rubber Band Library version 1.8.1 released

Version 1.8.1 of the Rubber Band Library audio time-stretching and pitch-shifting library is now available.

This is a bug-fix release, entirely source and binary compatible with 1.8.0 and earlier.

Following the exciting 1.8.0 release, which unified the codebase across GPL and commercial editions, 1.8.1 is the first release we recommend to clients wishing to deploy the library commercially for iPhone and iPad. See the README file for more about this platform, and the list of available build options in section 4b of the README for tuning parameters. As always, if you have any questions please don't hesitate to contact us.

Rubber Band Library version 1.8.0 released

Version 1.8.0 of the Rubber Band Library is now available.

Rubber Band is an audio time-stretching and pitch-shifting library and utility designed for musical applications. It allows you to change the tempo and pitch of an audio recording independently of one another.

The 1.8.0 release is the first to have a unified codebase across GPL and commercial editions. Now you can evaluate and integrate the library with your own code using the full commercial edition platform support, before deciding to buy. Accordingly, this release adds build support for Win32/MSVC, Android (with a Java JNI interface), and various new supporting libraries.

The library is source and binary compatible with version 1.7.

Version 1.7.0 of the Rubber Band Library is now available.

This release adds an option to adjust the handling of channels in stereo material, and fixes a number of bugs.

The library is binary compatible with version 1.6 for forward compatibility (values have been added to an existing enum). Code written to use 1.7 is not necessarily compatible with 1.6.

Dataquay version 0.8 released

Version 0.8 of Dataquay is now available, with the significant version number bump (over the previous 0.3 release) indicating a big step towards an API-stable 1.0 release.

Dataquay is a library that provides a simple, friendly C++ API for the Redland or Sord RDF data stores using Qt classes and containers.

This release fixes many details of the ObjectMapper code, improves the transactional store interface, and adds support for the lightweight Sord datastore as an alternative to Redland. See the changelog for more details.

Rubber Band Library version 1.6.0 released

Version 1.6.0 of the Rubber Band Library is now available.

Rubber Band is an audio time-stretching and pitch-shifting library and utility designed for musical applications. It allows you to change the tempo and pitch of an audio recording independently of one another.

This release adds a time-domain smoothing option to the library interface. This uses a window-presum FFT, introducing aliasing which is then smoothed using a sinc window. This can be used in combination with any of the existing processing control options. It will introduce audible time-domain artifacts for percussive transients, but the result may be successful for certain material that is not very amenable to stretching.

This release also fixes a silent-output bug for one channel when processing with the band-limited transients option, and adds support for the libresample library.

The library is binary compatible with version 1.5 for forward compatibility (values have been added to an existing enum). Code written to use 1.6 is not necessarily compatible with 1.5.

18th March, 2011

Rubber Band Audio Processor v1.2 now available, now in Mac App Store

Breakfast Quay announce Version 1.2 of Rubber Band Audio Processor, a straightforward, friendly, and useful program for messing with the tempo and pitch of audio recordings for musical purposes.

Dataquay version 0.3 released

Version 0.3 of Dataquay is now available.

Dataquay is a library that provides a simple, friendly C++ API for the popular Redland RDF data store using Qt classes and containers.

This exciting release introduces a complete object mapper capable of saving QObject hierarchies to the RDF data store and synchronising changes in both directions afterwards. There are other major changes here, including some very significant performance enhancements.

This version is not API compatible with the previous release -- most of the API is the same, but URI handling and the Transaction interface in particular have changed. However, the API is beginning to stabilise as we head toward 1.0.

3rd May, 2010

Rubber Band Library version 1.5.0 released

Version 1.5.0 of the Rubber Band Library is now available.

Rubber Band is an audio time-stretching and pitch-shifting library and utility designed for musical applications. It allows you to change the tempo and pitch of an audio recording independently of one another.

This release adds a key-frame mapping facility, for managing variable stretch ratios within a single offline time-stretch pass. It also includes a more reliable transient detection mode for soft instruments and band-limits the transient detectors to improve performance with compressed or lower-quality material.

The library is binary compatible with version 1.4 for forward compatibility. Code written to use 1.5.0 is not necessarily compatible with 1.4, as one new function and one enum have been added.

Rubber Band is an audio time-stretching and pitch-shifting library and utility designed for musical applications. It allows you to change the tempo and pitch of an audio recording independently of one another.

This maintenance release contains a fix for a hang when faced with some very peculiar stretch factors, and a fix for some incorrect threading condition usage. The commercial edition now contains support for the Accelerate framework on OS/X, and all editions are tested on Solaris in addition to other platforms. The library is binary compatible with version 1.3.

11th December, 2007

dssi-vst version 0.5 released

Version 0.5 of dssi-vst is now available.

This release comes with Javier Serrano Polo's VST-compatibility header, as previously distributed in LMMS. (Actually, this header was already compatible with dssi-vst -- no modifications to dssi-vst were necessary -- it's just that the header is now included in the package.) This permits it to be compiled without the official VST SDK and distributed under pure GPL. No guarantees are made as to the reliability of the results; your feedback is welcome, but please bear in mind that I will not do any development work on the compatibility header myself for legal reasons.

The 0.5 release is also (finally) compatible with version 2.4r2 of the official SDK, should you wish to use it.
