        SpectraSketch 1.1

        SpectraSketch 1.1

        This device reads image files as frequency spectrum data, allowing for a variety of effects including unique filtering, phase manipulation and sound generation, or simply encoding the image into the frequency spectrum of your track as a hidden message or easter egg. The frequency scaling of the image can be curved from linear to logarithmic, and constrained to a particular range of frequencies.

        Each colour channel has individual scaling for amplitude and phase and can be freely panned between the left and right channels, giving you fine control over the sound.

        In additive mode, a positive amplitude depth will produce sounds without any input, allowing this device to function as both an audio effect and an instrument in its own right.

        The image can be flipped, rotated and inverted to offer several options without having to edit the image, but there is also a reload button to quickly reload the image from file so that you can make changes in an external program and hear the changes easily.

        NOTICE: Due to using FFT for audio processing, this device requires 2048 samples of latency (approx. 184ms at 44.1kHz sampling rate), which may make it unsuitable for live performance applications where precise timing from a performer is required. Please take this into consideration before purchasing this device.

        14th April 2018 - V1.1 Update

        - Extended lower frequency limit to 0Hz.

        - Extended time range to 600 seconds.

        - Scan line position retained when switching between Auto and Mouse modes, allowing Mouse mode to function as a 'pause' of the scan.

        - Added new phase mode to allow colour values to map directly to phase value instead of phase change per FFT frame.
