The Quantization Error of Sápmi

Cultural assimilation operates identically to lossy audio compression; it measures the exact bandwidth of indigenous erasure by mathematically calculating and permanently deleting the frequencies that dominant ideologies render imperceptible.

An algorithmic filter discards yoik frequencies masked by dominant church hymns. · motion: Deleting the inaudible frequencies.

wall text

This installation models cultural assimilation as lossy psychoacoustic compression. Archival wax cylinder recordings of Sámi yoik are segmented into 32 critical frequency subbands via standard MPEG-1 Layer III algorithms. When overlaid with 19th-century Laestadian congregational hymns, a dynamic psychoacoustic model computes simultaneous masking thresholds: any yoik frequency rendered mathematically imperceptible beneath the dominant hymnal amplitude is stripped and permanently discarded. The suspended array of wooden transducers physicalizes the resulting quantization error, reproducing only the corrupted, surviving audio fragments. By treating religious indoctrination as bandwidth optimization, the work calculates the exact data loss required to engineer colonial silence.

shown: Installed permanently inside the rebuilt Kautokeino Church, vibrating the architecture exactly where the 1852 Sámi rebellion against religious and economic suppression occurred.

mechanism

MPEG-1 Audio Layer III (MP3) frequency subband filtering — Archival wax cylinder recordings of yoik are fed into a spectrum analyzer, dividing the raw indigenous vocalizations into 32 discrete frequency subbands.
1. Critical Band Analysis
Psychoacoustic Masking Threshold Determination — The algorithm overlays the yoik with audio of 19th-century Laestadian church hymns, mathematically calculating which yoik frequencies are rendered imperceptible by the louder, dominant hymnal tones.
2. Simultaneous Masking Calculation
Lossy Quantization and Data Discarding — The system permanently deletes the 'masked' acoustic data from the yoik recording, dynamically measuring the exact volume of data lost to calculate the quantization error of cultural memory.
3. Irreversible Bit Allocation
Pre-echo and Compression Artifact Generation — The surviving, heavily compressed file is amplified through bare wooden drum frames, generating audible metallic distortions that represent the highly processed remnants of the culture.
4. Decoder Ringing and Amplification

curatorial qa (machine verdict, unedited)

SCORE 3/5 after 2 attempt(s)
READS: The acoustic installation in the wooden chapel links archival measurement to colonial infrastructure, reinforced by the precise psychoacoustic masking diagram.
FAILS: The laser beam projection feels decorative and does not visually communicate frequency deletion, subband quantization, or psychoacoustic masking thresholds in real time.
