audio digitization

In scenes where audio and video are re-encoded and need to be synchronized, there are several basic principles to follow (otherwise the audio and video will be stuck and not smooth.) With audio AAC encoding frequency 44.1k, video H264 encode 25 frame rate for example): 1. Ensure that the audio and video frame arrival

Chapter One: FundamentalsThis chapter will show you how to start learning about Web audio APIs, which browsers support audio APIs, how to detect if an audio API is available, what an audio graph is, what an audio node is, how to connect each

In the FFmpeg ultra-detailed comprehensive tutorial---------------a sample of reading PC camera video data and sending it as a live stream with rtmp protocol is done in the camera live text, but the audio support is not implemented, so the example is further perfected in this article and the video synchronization problem of live stream is analyzed in detail. , a code example is also given. For the live stream, here only the synchronization of the send

First of all you should know what is ape? What can ape file play with? A: Ape is a lossless compression format for audio CDs. A: It is recommended to install Plug-ins with Foobar2000,winamp (the latest version is not available) can also play, WMP install Plug-ins can also play. 　 Okay, now do the prep, you need to be prepared with the following software: 1. EAC 095 2. Monkey Audio 397 (that is, the monke

1. Basic knowledge of I2S 1.1 I2s Introduction I2S bus, the abbreviation Inter-icsound, is a bus standard developed by Philips for audio data transmission between digital audio devices, which is specially used for data transmission between audio devices and is widely used in various multimedia systems. The I2S is also a synchronous serial communication interface.

The commonly used audio files are listed below.. AIFF is converted to uncompressed audio when importing, which is best for short sound effects.. WAV is converted to uncompressed

At present, there are a lot of users, when the mic is connected before the connection can not be successful. Here is a detailed description of the wiring method of the front microphone for your reference. 　　I. Intel specification for front-facing audio interfacesIntel has regulated the front audio interface sockets, cable, and pin names for motherboards and chassis in the Front Panel I/O connectivitydesign

Introduction and comparison of common audio protocols for conference TV white PaperFirst, the digital audio principle: The sound is actually a kind of energy wave, therefore also has the frequency and the amplitude characteristic, the frequency corresponds to the time axis, the amplitude corresponds to the level axis. Usually the ear can be heard in the frequency of 20Hz to 20KHz of sound waves known as aud

Audio, English, or you might see an audio output or input on the back panel of a VCR or VCD. This allows us to interpret the audio in a very popular way, as long as it is a sound that we can hear and transmit as an audio signal. For the physical properties of audio because i
