// Behind the Signal

PROCESS

How memory becomes signal.

CASSETTE TO DIGITAL

The ritual of capture. Every tape tells a different story based on its age, storage conditions, and playback device.

Equipment

  • Sony Walkman WM-D6C (modified)
  • Focusrite Scarlett 2i2 interface
  • Audacity for initial capture
  • iZotope RX for restoration (when needed)
  • Custom Max/MSP patches for real-time processing

1. PREPARATION

Clean the tape heads with isopropyl alcohol. Fast-forward and rewind the tape once to reduce tension inconsistencies. Let the Walkman warm up for 10 minutes.

2. CAPTURE

Record at 24-bit/96kHz to preserve all artifacts. Never use noise reduction during capture—the noise is part of the signal. Record the entire tape, including leader silence and mechanical sounds.

3. ANALYSIS

Listen to the full recording before any editing. Note timestamps of interesting degradation patterns: wow, flutter, dropout, oxide shedding. These become compositional elements.

4. EXTRACTION

Isolate fragments based on emotional resonance, not technical quality. A corrupted memory is still a memory. Export stems for layering in Ableton.

Degradation is not failure. It's transformation. The tape remembers differently than we do—its version of events is equally valid.

ABLETON WORKFLOW

Structure for chaos. A consistent organizational system allows for spontaneous composition while maintaining navigability.

Track Organization

Tracks 1-8Source material (field recordings, tape captures)
Tracks 9-16Processing chains (granular, spectral, time-stretch)
Tracks 17-24Synthesis layers (modular, soft synths)
Tracks 25-32Spatial processing (reverbs, delays, panning)
Return ALong reverb (6+ seconds)
Return BTape saturation/degradation
Return CPitch shifting/harmonizing

Key Techniques

  • Color-coded clips by source type (blue: field, orange: tape, green: synth)
  • Session view for improvisation, arrangement view for composition
  • Max for Live devices for custom processing
  • Freeze tracks early to preserve CPU for real-time manipulation
  • Export stems at every major decision point (version control for sound)
The DAW is an instrument. Learn its shortcuts until they become muscle memory. Then forget you're using software at all.

FIELD RECORDING METHODOLOGY

Listening as practice. The microphone reveals what the ear normalizes.

Equipment

  • Sony PCM-D100 (primary recorder)
  • Zoom H6 (backup/multichannel)
  • DPA 4060 lavaliers (hidden recording)
  • Sennheiser MKH 8040 (detailed capture)
  • Contact microphones (handmade, piezo-based)

PATIENCE

Arrive early. Stay late. The interesting sounds happen between the expected ones. A 4-hour recording session might yield 30 seconds of usable material.

INVISIBILITY

The best recordings happen when you disappear. Small recorder, no visible equipment, minimal movement. Become part of the environment.

DOCUMENTATION

Voice memos after each recording: location, time, weather, emotional state, technical settings. Context transforms sound into memory.

FAILURE

Record everything, even when it seems wrong. Wind noise, handling sounds, equipment malfunction—these accidents often become the most valuable material.

We don't capture sound. We capture our relationship to a moment in space and time. The recording is a collaboration between environment, technology, and attention.

GRANULAR SYNTHESIS

Dissolving time. Breaking sound into particles to rebuild it as something new.

Patch Structure

Parameters

Grain Size1ms - 500ms

Smaller = more texture, larger = more recognizable source

Grain Density1 - 200 grains/sec

Low density = rhythmic, high density = cloud/texture

Position Randomization0% - 100%

0% = sequential reading, 100% = complete time dissolution

Pitch Variation-2 to +2 octaves

Per-grain randomization creates harmonic clouds

Every sound contains infinite other sounds. Granular synthesis is archaeology—excavating the hidden structures within a waveform.
