CLI

Glacier EQ CLI

Offline, synchronous, no GUI. Data goes to stdout, diagnostics to stderr. Pipe it.

Profiles & Math

Local storage defaults to standard OS app data directories. Override with GLACIER_EQ_HOME.

# Inspect and normalize to DAC limits
glacier-eq-cli inspect profile.txt
cat profile.txt | glacier-eq-cli normalize - 3302:43e8

# Store and list
glacier-eq-cli profile save Daily profile.txt
glacier-eq-cli profile list
glacier-eq-cli profile show Daily
glacier-eq-cli profile delete Daily --yes

# Frequency response CSV
glacier-eq-cli response profile.txt > response.csv

AutoEQ

Provide two frequency,dB files. Output is AutoEQ standard format.

glacier-eq-cli autoeq measurement.csv target.csv \
  --bands 10 --steps 3000 --smooth ie --sample-rate 48000

Hardware (HID)

Direct USB access (desktop only). Omit --device if exactly one supported DAC is plugged in. Mutations require --yes. Push always reads back to verify.

# List supported devices and their paths/IDs
glacier-eq-cli hardware list

# Pull current EQ from device
glacier-eq-cli hardware pull > current.txt

# Push to RAM or flash
glacier-eq-cli hardware apply tuned.txt --yes
glacier-eq-cli hardware push tuned.txt --device 3302:43e8 --yes
