If a VoIP device configured for μ-law receives an A-law stream (or vice versa), the result is garbled, metallic-sounding audio. G711.org provides the tools to detect and convert between these two standards seamlessly.
The standard describes a method for converting analog audio signals into digital signals using pulse-code modulation (PCM). PCM is a technique for encoding analog signals into digital form by sampling the signal at regular intervals and quantizing the amplitude of each sample. The G.711 standard specifies the parameters for this process, including the sampling rate, bit rate, and quantization.
for f in *.ulaw; do g711org -i "$f" -f ulaw -o "$f%.ulaw.alaw" -t alaw done
As long as G.711 exists, tools like G711.org will be necessary. In fact, the site’s maintainers could expand to include G.711.1 (wideband extension) or G.711.0 (lossless compression) in the future. For now, G711.org remains the most accessible, no-installation-required utility for the job.
While G711.org is excellent, it is not perfect. Understanding its limitations is important.
