If you want a high-definition codec for wideband, then you should look at G.722 HD. This codec was approved in 1988, and it is free to use for everyone. Without any perceivable latency, this codec can help to improve the speech quality of your calls. Its HD voice has a sample rate of G.711 at 16 bits, but the transmission rate remains the same at 64 kbit/s.

It is now freely available because its patent has expired. Another HD voice codec, G.722.2, offers high-definition voice quality over smaller bandwidth transfer rates. However, the current “gold standard” of the wideband audio codecs is called Opus, and it's the default codec that's used by all WebRTC technology and apps currently available.

Usually, the human hearing bandwidth is 20Hz-20kHz; the audio sampled can be at a rate above 40kHz. (Usually, 44.1KHz is preferred). 48000 kHz is the most considerable supported sample rate. Most producing equipment will work at either 44100Khz or 4800Khz. It suggests you match the sample rate of your stream with the help of your production tool.

FLAC is a non-proprietary, open-source codec great for professionals who require high-quality audio. They are capable of providing a resolution of up to 32-bit, 96kHz, which makes them considerably better than even CD quality! However, they’re around six times larger than lossy audio files and aren’t compatible with every device and software. ALAC:
VoIP Codecs Explained - How to Improve Call Audio Quality

The G.711 codec offers some of the best sound quality. However, it also requires the most bandwidth. This codec requires at least 96Kbps of bandwidth per line. If you want slightly better audio quality, you can use this codec with less compression. But that will require 112Kbps or 128Kbps of bandwidth per line.

The codecs generally used on the web that are used for voice-only encoding are G.722 and AMR. AMR is a narrowband codec, encoding only the frequencies between 200 Hz and 3,400 Hz at bit rates typically around 7.4 kbps, while G.722 is a wideband codec that expands the audio bandwidth to 50 Hz to 7,000 Hz at much higher bit rates—usually 64 kbps.
VoIP Codecs + Bandwidth = Your Call Quality | GetVoIP

Codecs work by encoding and decoding audio signals. The most commonly used codec is called G.711, and uses 64 kilobits per second plus additional overhead for safety, which can work out to an IP bandwidth of 80-90Kbps. But, G.711 uses no compression. You can use other codecs that compress data to use less bandwidth, at a lower quality, but still suitable for …
