Show Frequency Ruler: Shows a frequency ruler along the left side of each sample in the
main display. There are dierent options for the way in which frequencies are represented
in the spectrogram:
Linear: Linear scale means that Hertz are linearly spaced on a screen.
Mel and Bark: Mel and Bark scale are frequency scales commonly found
in psychoacoustics, i.e. they reflect how our ear detects pitch. They are
approximately linear below 0.5 kHz and approximately logarithmic above
that. Mel scale is reflecting our perception of pitch; equal subjective pitch
increments produce equal increments in screen coordinate. Bark scale is
reflecting our subjective loudness perception and energy integration. It is
similar to Mel scale, but puts more emphasis on low frequencies.
Log: In this mode, dierent octaves occupy equal screen space. The screen
coordinates are proportional to the logarithm of Hertz down to 100 Hz.
Extended Log: This extends the logarithmic scale down to 10 Hz, so that it
puts even more attention on lower frequencies.
Spectrogram Type: Select the type of spectrogram calculation algorithm that is used
to visualize your samples. In Manual and Precise mode, you can set the FFT size for
spectrogram calculation in samples.
Sample & Selection Options
When Loading a Sample: When a sample is dropped into Iris, you can set how Iris 2 will
assign a root note to that sample.
Auto-detect root note: Iris will analyze the current audio file and its harmonic
content to determine the fundamental frequency of that sample. Iris will then
automatically set the root note for the newly loaded sample to the determined
fundamental frequency.
Auto-detect Root Note can be manually engaged for any sample or refined
with any selection by right-clicking on the spectrogram at any time. This is
true, even if Auto-detect Root Note is not the selected mode.
Set root note to C4: Iris will automatically set the newly loaded sample’s root
note to C4, regardless of the sample’s pitch.
