Photosounder: Transform Images into Soundscapes

From Pixels to Pads: Crafting Pads and Atmospheres with Photosounder

Introduction Photosounder is a unique granular spectral instrument that converts images into sound. By treating pixels as spectral energy, it lets you sculpt evolving pads and immersive atmospheres from any picture — photos, paintings, fractals, textural scans, or hand-drawn graphics. This article shows a practical, step-by-step workflow to create rich pads and soundscapes, plus creative techniques and tips to get musical results fast.

1. Choose or Create the Right Image

• Texture matters: Soft gradients, clouds, smoke, fabric folds, or brush strokes map well to smooth pad timbres. High-contrast, noisy images yield gritty textures.
• Aspect ratio & resolution: Wider images emphasize stereo/panning spreads when using Photosounder’s stereo controls. Use 1024–2048 px width for detailed spectral content; lower resolutions can sound smoother.
• Color vs. grayscale: Photosounder uses luminance for spectral amplitude; color can be converted to grayscale or the color channels can be mapped separately for layered results.
• Quick sources: Photos of skies, macro shots of rust/wood, scanned watercolor washes, or generated Perlin noise/fractals.

2. Basic Import and Initial Sound

• Open the image in Photosounder and immediately audition the default render.
• Adjust the time scale (duration) to set how long the pad evolves. Longer times produce slow-moving atmospheres; shorter times give rhythmic or pulsing pads.
• Use the View modes (spectral, waveform) to locate strong harmonic zones and transients to emphasize or tame.

3. Sculpting the Spectrum

• Brush tools: Paint to add or remove energy from frequency bands. Smooth strokes across horizontal bands create continuous harmonic pads.
• Blur & smudge: Apply Gaussian blur horizontally to smear spectral energy into lush, sustained harmonics; vertical blur affects transient density and attack.
• Contrast & levels: Increase contrast to accentuate harmonics; reduce to soften harshness. Use levels to shift energy toward low or high-frequency bands.
• Selective editing: Isolate frequency regions with selection tools and apply independent processing (e.g., boost lows, attenuate harsh mids).

4. Harmonic Control and Pitching

• Pitch shifts: Use Photosounder’s resynthesis pitch controls to transpose the whole
