This section describes several python audio processing libraries and python audio processing libraries. 　　1. eyeD3 Search for python mp3 process directly on google. This third-party library is recommended. Let's take a look at the official introduction.About EyeD3 is a Python tool for working with audio files, specifically mp3 files containing ID3 metadata (I. e.

Introduction Audio and video are the main methods for multimedia applications to provide information to users. These audio and video data generally have a high sampling rate, and the compressed raw data has practical value, otherwise, it will not only occupy a large amount of storage space, but also have a low validity rate during playback or network transmission. Therefore,

1 PCM InterfaceFor different digital audio subsystem, there are several interfaces between microprocessor or DSP and audio devices for digital conversion. The simplest audio interface is the PCM (Pulse coded modulation) interface, which consists of a clock pulse (BCLK), a Frame sync signal (FS), and a receive data (DR) and send data (DX). At the rising edge of th

in the process of deepening understanding, as well as during the discussion with you after the article, worried that the successor according to this one year ago detours, Bill felt the need to make an update on the article, point out the detour to avoid misleading later. 1. The beginning of their own is the AECM, NS, VAD, AGC each module extracted separately use, now seems to be troublesome, and the effect is not very ideal. If everyone's project has no special requirements, large can be the en

converts a continuously varying analog signal to a digital encoding by sampling, quantization, and coding in three steps.Lossy and LosslessAccording to the sampling rate and sample size can be learned that, relative to the nature of the signal, audio encoding can only be infinitely close, at least the current technology can only be so, relative to the nature of the signal, any digital audio coding scheme i

Doing H5 games will inevitably encounter the need to play background music or sound effects. The first response to this requirement was to use the audio tag in H5 to implement it, but in the process of implementation it was found that there were many problems.1. Only a single audio can be played (on some devices, including iOS). What do you mean? This means that if you play the sound effects while playing t

1 PCM InterfaceFor different digital audio subsystems, there are several microprocessor or interfaces used for digital conversion between DSP and audio devices. The simplest audio interface is the PCM (pulse Coding Modulation) interface, which consists of Clock Pulse (bclk), frame synchronous signal (FS), and receive data (DR) and data transmission (dx.

AAC Audio ConverterIntroduction: audio files in any format can be transcoded and compressed into AAC MPEG-4 (m4a) format. It can be applied to the app that needs to transmit sound files, so that it can compress a large volume of sound files (such as PCM) into a small AAC for transmission.Http://ios.itmdc.com/forum.php?
