sampling - Why is telephone audio sampled at 8 kHz ...
https://dsp.stackexchange.com/questions/22107/why-is-telephone-audio-sampled-at-8-khz
It was thought to provide a good trade-off between quality and bandwidth. Actually a single voice signal occupies 8 kHz, not 8 kbps, of bandwidth. Each sample is quantized into 8 bits, yielding a rate of 64 kbps which is used universally. Further reading: http://en.wikipedia.org/wiki/Digital_Signal_0.

What Is Audio Bitrate. Audio bitrate defines the amount of data that is stored in the sound file you are listening to. Every audio file has a “bitrate” associated with it. Every second of an audio recording contains a certain amount of data or bits. When it comes to sound files this is calculated by the number of kilobits of data per second. For example, a 128 kbps (kilobits per …

The right bitrate for a file depends on what you want to use that file for and the means of delivering the audio. In general, a high bitrate means high-quality audio, provided the sample rate and bit depth are also high. More information, in a very general sense, means better sound quality. Audio CD bitrate is always 1,411 kilobits per second (Kbps).

An audio frame is the group of audio samples for an instance of time that come from one or more audio channels. The most common values for the sampling rate is the aforementioned 8kHz (most common for telephone communications), 44.1kHz (most common for music CDs), and 48kHz (most common for audio tracks in movies).

Audio bitrate is the amount of data (or bits) that are processed in a certain amount of time. The most common way to measure bitrate is in kilobits per second. When you download a track off Beatport, the MP3 will be in 320kbps. This …
Understanding Audio Quality: Bit Rate, Sample Rate ...

As the bit rate increases the amount of data streamed per second increases at a good sampling rate to produce the replica of analog signal with more bit depth(16 for audio) thus increasing the bandwidth and file size to produce the best audio quality. Some of the bit rate and sample rate preferred are given below: For MP3format the Mp3 streaming bit rates and sample …

Each frame is ten milliseconds long and contains 80 audio samples. The bitrate for one direction of this non-HD codec is 8kbit/s. Since the compression is higher, you’re able to make more calls from your network at once. That said, a few VoIP providers may not support the G.729 codec. Music and other non-verbal audio can sound choppy.
