So, PCM isn't the thing you meant here. PCM just means Pulse-code modulation, you're probably thinking of a specific non-linear PCM and maybe that was even the default for some particular hardware or software you used, but that's not what PCM itself means and these days almost everything uses Linear PCM.
- userbinator 1y agoI think G.711 PCM is what the OP meant.
- tialaramex 1y agoWow. G.711 is extremely obsolete. Interpreting PCM as G.711 (which is from the 1970s) is about similar to if somebody said "Windows" but meant Windows 2.x the 1980s DOS-based Microsoft GUI. I guess I don't have to feel like I'm the oldest person reading HN.
- userbinator 1y agoIn the telco industry, "PCM" or more precisely "PCMA" and "PCMU", refers to G.711. It's still the default fallback for VoIP applications.
