Verified usage

Verified import paths — ran on the pinned version, not inferred.

alaw2linear

✓ from g711 import alaw2linear

✗ import g711; g711.alaw2linear(...)

Module-level function; no class wrapper.

ulaw2linear

✓ from g711 import ulaw2linear

✗ from g711 import ulaw; g711.ulaw.ulaw2linear(...)

No submodules; functions are flat.

G711Exception

✓ from g711 import G711Exception

✗ import g711.exceptions

Exception class is top-level, not in a submodule.

Encode and decode 16-bit linear PCM samples to/from 8-bit G.711 A-Law/u-Law bytes.

from g711 import alaw2linear, linear2alaw, ulaw2linear, linear2ulaw # u-Law encode/decode sample_linear = 1234 ulaw_byte = linear2ulaw(sample_linear) # returns int 0-255 restored = ulaw2linear(ulaw_byte) # A-Law encode/decode alaw_byte = linear2alaw(sample_linear) restored_alaw = alaw2linear(alaw_byte) print(f"u-Law: {ulaw_byte} -> {restored}") print(f"A-Law: {alaw_byte} -> {restored_alaw}")

Debug

Known issues

gotchaFunctions expect 16-bit signed integer input (-32768 to 32767). Out-of-range values may produce undefined behavior or silently wrap.

fix

Always clamp your input to the valid range before passing to linear2alaw/linear2ulaw.

affects: all

gotchaThe library returns integer values (0-255) for encoded bytes, not bytes objects. To write to a file, you must pack them with struct.pack or bytes().

fix

Use `encoded_bytes = bytes([linear2ulaw(sample) for sample in samples])` to write as raw bytes.

affects: all

deprecatedNo official deprecations. Older versions (pre-1.6) had different function names (e.g., ulaw_encode instead of linear2ulaw).

fix

Use current function names: linear2ulaw, ulaw2linear, linear2alaw, alaw2linear.

affects: <1.6.0
