Message: [QUOTE="Shamiso, post: 92592, member: 160"] DeltaScope 1.2 can color its waveform from red in the bass through green in the mids to violet at the top. Mixed sounds can show several regions at once, so a kick under hi-hats does not have to collapse into one flat color. The point is not decoration. [B][URL='https://goldmidi.com/community/threads/apollo-view-expands-deltascope-to-windows-and-aax.77962/']DeltaScope’s Color by Frequency view[/URL][/B] adds spectral information to the waveform you already use for timing and amplitude, which means one display can show where a transient happens and roughly which frequency range is carrying it. A normal waveform only tells you how amplitude moves over time. Two sounds can produce peaks of similar height while living in very different parts of the spectrum, and a plain trace will not spell out the difference. [HEADING=2]Color adds frequency without replacing the waveform[/HEADING] Red does not mean loud, and violet does not mean quiet. In this view, color points toward frequency content while the waveform shape still carries the usual time and amplitude information. A tall red section therefore means something different from a short violet section. This becomes useful on layered material. A kick can dominate the low-frequency color while hi-hats add violet or upper-range detail over the same moment, so the trace starts revealing which spectral regions are active without forcing you to move your eyes to a separate analyzer. Broadband sounds are less tidy. A snare, distorted bass, saturated vocal, or full mix can contain energy across a wide range, so a single instant may show blended or shifting colors rather than one clean band. Treat the color as a spectral cue, not a label naming the instrument. The same logic applies when DeltaScope colors its spectrum curves and peak-hold lines. Version 1.2 lets the main and sidechain signals use separate switches, so you can keep frequency coloring where it helps and leave another trace visually simpler when comparison matters more. [HEADING=2]Brightness and pitch are not the same thing[/HEADING] High-frequency color can make a sound look brighter, but brightness is not identical to musical pitch. A low note with strong upper harmonics can carry plenty of high-frequency energy, while a higher note with a soft spectrum can look less top-heavy than you might expect. The [B][URL='https://phys.unsw.edu.au/jw/reprints/SchWolTarICMPC8.pdf']spectral centroid of complex instrumental textures[/URL][/B] is one useful way to describe where spectral energy is centered, and perceived brightness tends to follow that distribution more closely than fundamental pitch alone. Frequency-colored waveforms make the distinction easier to notice because the color follows spectral content rather than the note name printed on a piano roll. Distortion makes this obvious. Feed a clean bass sine into saturation and the fundamental can stay at the same pitch while new harmonics appear above it. The waveform shape changes, but the new upper-frequency color gives you another clue that the sound has become spectrally richer rather than simply louder. Filtering works in the opposite direction. Roll off the top of a noisy percussion loop and the waveform may retain similar transient timing while the violet and upper-range content recedes. You can see the tonal shift without pretending the waveform itself has become a spectrum analyzer. [HEADING=2]A colored waveform is still not a spectrogram[/HEADING] A spectrogram dedicates one axis to time, another to frequency, and uses color or brightness to represent energy at each time-frequency position. A frequency-colored waveform keeps the ordinary waveform geometry and paints spectral information onto it instead. The trade-off is important. A spectrogram can show several simultaneous frequency bands as separate vertical positions, making harmonics, resonances, whistles, and moving tones easier to isolate. A colored waveform compresses more information into one trace, so it is faster to read but less forensic. Use the colored waveform when timing still matters most. Drum transients, clipped peaks, note attacks, pauses, and waveform asymmetry remain easy to locate while the color hints at what part of the spectrum is responsible. Switch attention to the spectrum or a proper spectrogram when you need exact frequency separation. Color can also mislead if you start treating it as a diagnosis. A red-heavy section is not automatically muddy, and violet does not mean harsh. The display tells you where energy sits, while the musical judgment still depends on level, context, masking, arrangement, and what the sound is supposed to do. Put a saturated bass before and after the processor on two DeltaScope instances and watch the upper-frequency colors appear while the fundamental stays put. Do the same with a low-pass filter and the reverse happens, with the upper colors fading while the transient timing can remain almost unchanged. Those changes give you a fast way to spot what the processor added or removed before you move to a more exact spectral measurement. [/QUOTE]
