1.4.2

Full Changelog: 1.4.1...1.4.2

1.4.1 - Fixed zita range constants

This is a quick hotfix for zita parameter validation to ensure that the RT60Low and RT60Mid aren't allowed to cause the audio buffer to die.

• Tweak minimum value for RT60Low and RT60Mid on zita parameter validation to 0.05 (up from zero)

  • 0.05 should be safe and not cause the audio buffer to nuke itself

• Tweak maximum level ranges for EQ1, EQ2 and Level parameters on ZitaReverb to 45 decibels (up from 20)

  • This should allow more leeway when tuning certain types of effects (e.g. cutting lows and boosting highs for radio-like effects)
  • This should also allow more fun :)

Enjoy!

1.4.0 - New pitch shift filter

What's changed

• Converted Zita reverb filter to a fully managed implementation.

  • This is fully analagous to the unmanaged sp_zitarev implementation, but is much easier to manage.

• Sealed Zita reverb until the API is more hardened since things are still in flux right now.

• Add new time-domain-based pitch shift filter

  • This is fully analagous to the unmanaged sp_pshift implementation, but again, is much easier to manage.

• Updated example program to be more robust and include outputs for the currently-implemented filters.

1.3.3 - Fix issues with Mono

What's Changed

• Fix FromOther using "in" for the parameter which causes issues with mono runtime by @Frooxius in #1

New Contributors

• @Frooxius made their first contribution in #1

Full Changelog: 1.3.2...1.3.3

Helpful constants - 1.3.2

Included now are useful constants which define the default, min and max values for valid ZitaReverb inputs.

• Add ZITA_*_DEFAULT/MIN/MAX constants which define the default, min and max values for ZitaReverb
• Important! Change an internal inline _clamp method to be static so that unnecessary memory allocations are avoided on .NET Framework
  • If you're experiencing higher-than-normal memory pressure on version 1.3.1, please update!

Parameter validation - 1.3.1

This release includes some changes to how parameters are copied with FromOther() and allows you to now validate parameters to make sure users don't explode their ears.

• Changed FromOther<T>(T zita, IZitaFilter other) to FromOther<TFrom, TTo>(TFrom zita, TTo other) instead of always requiring an object of type IZitaFilter`.
  • This allows you to avoid boxing should you decide to use something like the ZitaParameters struct with it now.
• Added EnsureValidParameters() extension method so that you can validate input parameters given to an IZitaFilter type.
  • Also adds EnsureValidNum() extension method to validate floats with an optional fallback value.

Enjoy!

Less hassle for zitarev compute - 1.3.0

This release of SharpPipe includes changes that fix a crash in unity and remove a lot of hassle from processing samples.

• Change function signature of ZitaReverb.Compute to now process input samples in chunks.
  • This now means you can pass arbitrarily-sized input data and define how big the chunk size is for processing.
• More careful handling of reorientation of interleaved stereo samples on the stack
  • Use spans and properly fix buffers in place whilst calling into P/Invoke
  • This appears to fix a crash on Unity 2019.4.19f1, where a null pointer would seemingly be passed regardless of the validity of input data.

Enjoy!

Bulk sample processing - 1.2.2

This release includes the ability to process samples in bulk rather than one at a time, vastly increasing the throughput potential for realtime audio processing.

• Added overload to Compute() that takes two spans of floats indicating an input and an output span of interlaced stereo samples.
  • The input and output can be the same destination if the goal is to compute samples in-place.

Helper hotfix - 1.2.1

• Quick change to ensure that 'FromOther' returns the filter that was modified in case the filter is implemented as a value type
• Change 'FromOther' to be a generic T of IZitaFilter for better type clarity

Parameters and example updates - 1.2.0

This release includes the addition of the ZitaParameters struct, which also implements the IZitaFilter interface. This can be used to easily pass parameters to/from existing objects that implement them. The example program has also been updated to showcase how to use it and now also references the SharpPipe project directly.

• Add ZitaParameters struct for easily passing parameters around
• Update example to use direct project reference instead of nuget package
