PCM audio(Pulse-Code Modulation) is one type of digital audio. Ananalog electrical signalfrom a microphone is converted to digital form. In AV-applications PCM is a data-uncompressed alternative to Dolby Digital technology. PCM is representation of an analog acoustic waveform as sequence of samples...

Is it configurable? Why is private displayed in HiLog information when the format parameter %d or %s is specified? What should I do if the hilog.debug log cannot be printed? How do I control the log output level based on the environment? How do I locate application performance ...
In linear PCM audio, a packet is always a single frame. In compressed formats, it is typically more. A packet defines the smallest meaningful set of frames for a given audio data format. In linear PCM audio, a sample value varies linearly with the amplitude of the original signal that it...
What Is G.711? 解決策 G.711, also known as Pulse Code Modulation (PCM), is a commonly used waveform codec. G.711 uses a sampling rate of 8,000 samples per second. Non-uniform quantization (logarithmic) with 8 bits is used to represent each sample, resulting in a 64 kbit/s bit rat...
