Splat v1.6

What's new?

• improved bm.py to run more benchmarks and pickle the results #13
• all levels are now treated as linear values, use dB2lin for levels in dB
• add compare.py to compare two sound files
• SPLAT_FAST build option to use SIMD on ARM NEON and x86 SSE2, 32-bit float #14
• _splat.c now only contains the Python bindings, implementation is moved to multiple C files

API changes

• splat.interpol.PolyList.pols new property to get the polynomials #13
• splat.interpol.spline now has a new dB2lin option to define a Spline in dB
• splat.data.Fragment.lin2dB and .dB2lin to convert a whole fragment
• splat.data.Fragment.get_peak returns dictionaries with max and min

Bug fixes

• fix double free in splat_signal_free
• fix and improve phase values using modulo

Splat v1.5

What's new?

• Basic sequencer support #2 #10
• 180x faster spline interpolation signal with native C implementation #7
• Manual updated, reviewed and improved

API changes summary

• splat.sample_types sample types consolidated with strings identifiers #12
• splat.interpol.PolyList.signal new property to use native spline signal implementation #8
• splat.data.Fragment.get_peak() new method to get maximum, minimum and average
• splat.data.Fragment.grow() new method to increase the fragment length if needed
• splat.data.Fragment.save() new argument normalize to normalize by default
• splat.gen.Generator.run() new argument length as alternative to end

Main bug fixes

• Levels (gains) can now be set with integers as well as floats and signals #5 #11
• Fix test.SignalTest pass on i386
• Fix error reporting with internal signals implementation

Splat v1.4

What's new?

• Manual layout reviewed and improved
• New manual section about scales #1
• More raw audio sample formats (now 8, 16, 24 bit integers and 32, 64 bit floats)
• Extra file formats with audiotools when present (Ogg, MP3, Flac)
• splat.interpol.freqmod function to easily create a frequency modulation signal using a spline
• Now available on https://pypi.python.org/pypi/verdigris.mu-splat
• Benchmark script bm.py using benchmark #3

API changes summary

• splat.interpol.spline is now a function that returns a PolyList object
• splat.gen.Generator._run function has a new absolute origin argument - useful with signals
• splat.scales.Scale.abs_cycles new property to use absolute notation

Main bug fixes

• Fixed memory leak in function signal
