v1.5.1

Release date: 2020-02-17

Changelog:

Maintenance / bugfixes / corrections:

• Several small optimizations and corrections.
• Make proper use of fmt.Errorf(...) function.
• Make use of real FFT / IFFT for reducing filter order.
• Remove now-dead code from filter package.
• Make critical sections in level meters shorter.
• Increase coverage of unit tests for oversampling package.
• Reduce lock contention during FFT.
• Improve code of level meter and spatializer implementation.
• Write new test cases for new multi-channel level meter implementation.
• Clean up other code as a result of the refactoring.
• Make the Fourier transform instantiable to avoid locking permutation buffers.
• Add performance analysis / discussion document.

v1.5.0

Release date: 2019-12-18

Changelog:

New features / enhancements:

• Implement oversampling for effects making use of non-linear amplification. Oversampling of non-linear processes prevents aliasing distortion.
• Implement new "oversampling" package implementing on-the-fly sample rate conversion, anti-aliasing filters, and decimation.
• Implement unit-tests for the new package.
• Update "excess", "fuzz", "overdrive" and "distortion" effects unit to make use of oversampling and provide a new parameter for it.
• Update UI code to provide localized string for the new parameter.
• Update the documentation to explain the new feature.

Maintenance / bugfixes / corrections:

• Fixed a race condition in the power amplifier simulation. The race condition could lead to incorrect results, especially while batch-processing files.
• Fixed an incorrect length field in the oversampling module leading to incorrect results while processing the first block of audio.
• Increment minor version number: v1.4.0 --> v1.5.0

v1.4.0

Release date: 2019-10-19

Changelog:

New features / enhancements:

• Added support for physical units on numeric parameters.

Maintenance / bugfixes / corrections:

• Update to latest version of pure-knob.
• Increment minor version number: v1.3.3 --> v1.4.0

v1.3.3

Release date: 2019-07-17

Changelog:

Maintenance / bugfixes / corrections:

• Updated to latest version of pure-knob.
• Make JavaScript comparison more specific.
• Name all JavaScript event parameters e.
• Add comment for global variable.
• Several other improvements to the code.
• Increment patch version number: v1.3.2 --> v1.3.3

v1.3.2

Release date: 2019-05-30

Changelog:

Maintenance / bugfixes / corrections:

• Modify Makefile to build optimized as well as unoptimized (*-debug) binaries. Optimized binaries should be used in production as these allow you to achieve much lower latency without audio dropouts. Unoptimized binaries should be used for debugging and for reporting issues.
• Update the changelog.
• Increment patch version number: v1.3.1 --> v1.3.2

v1.3.1

Release date: 2019-05-18

Changelog:

Maintenance / bugfixes / corrections:

• Fix a bug which causes go-dsp-guitar to terminate with an index out of bounds exception when batch-processing audio files containing only a single channel.
• Correct compiler flags for go version >= 1.10.
• Fix several issues with the build system when cross-compiling go-dsp-guitar.
• Correct the changelog.
• Increment patch version number: v1.3.0 --> v1.3.1
• Update README.md.

v1.3.0

Release date: 2019-03-02

Changelog:
