Version 0.5

- The offline example is changed to show how to use time stretching.
- SuperpoweredRecorder extended with simple WAV writer functions.
- Bugfixes in pitch shifting and mono mixer.
Version 0.6

SuperpoweredBandpassFilterbank
- New feature!
- A bank of arbitrary number of bandpass filters.
- Good for real-time analyzers (RTA) or offline usage.
- Very simple to use: just set up the frequencies and widths, and call
process().
- In addition to the frequency bands, the sum and peak of the incoming
signal is returned too, so you get the average and peak volume.

SuperpoweredAnalyzer
- New feature, an offline analyzer to detect several important audio
features.
- Bpm (beats per minute) detection to get the tempo.
- Key detection to get the main harmonic chord of the music.
- Easy helper tables to get the key in musical, Camelot or Open Key
notations.
- Loudness/peak analysis to detect the average and peak volume.
- The average loudness of the “loud” music parts is returned as well
(excluding breakdowns and other quiet parts), to get a “real” average
loudness data.
- Beatgrid information shows where the beats and bars start (beat and
bar onset detection).
- Average and peak waveform data in compact form with 150 points/sec
resolution.
- Compact music structure data, average decibels in 1 points/sec
resolution.
- Online analyzer will come later (until then you can use the
SuperpoweredBandpassFilterbank for RTA).

SuperpoweredIOSAudioOutput
- Sample rate is not “forced” to the hardware anymore, but the
hardware’s native sample rate is accepted.
- You can set the preferred minimum sample rate to always have good
sound quality.
- The preferred buffer size is set by milliseconds now, as the sample
rate may change dynamically.
- iOS 8 has multiroute audio session bugs with several USB audio
devices (silent output). Now the object turns on the multiroute audio
session category for 2-channels USB/HDMI devices only. Multichannel
audio devices are handled with other audio session categories (no
multiroute session necessary).

Superpowered3BandEQ
- Simplified parameters. Just set the 3 bands (simple float variables)
and that’s it.
- Kill is enabled for a band under -40 decibel (0.01f).

SuperpoweredAdvancedAudioPlayer
- Pause method is enhanced with optional decelerate parameter for
stopping with momentum. Works with slip mode too. Good for turntable
motor effects.

SuperpoweredDecoder
- New method to search for the first audio sample. Good for cutting
initial silence.
- Parameters: how far to search for, loudness threshold.
- A 0 loudness threshold will cut digital silence, while -49 decibels
is good to search for the beginning of vinyl rips.

SuperpowerdMixer
- The Apple 8.24 format conversions are removed as this format is
officially deprecated.
- New feature: processPFL method to create a pre-listening signal for
any mixer, with channel switches and optional channel output level
processing.
