Lesson three the hardware operation example of recording The following is mainly about the hardware use and operation of recording: 1. Handling the recording environment, to ensure quiet and sound insulation (preferably to do the sound absorption processing, but the amateur conditions are not good, this is a bit difficult, I can not do, hehe). 2. Fixed the mic

The general sound visualization makes the spectrum map on the line:But I don't think the spectrogram can see what the sound is, so be sure to make a sonogram, both of which get information about the frequency of the sound.This paper studies the two examples of Auriotouch and Pitchdetector on the official web, and integrates the main code obtained by Auriotouch's audio-visual display and pitch detector frequency to the previous section "OC Development

Note: The purpose of this article is mainly for the laptop headphone jack No response problem, that is, the headset inserted but the computer sound still through the speaker. First, open the Control Panel, the sound to see if the local sound card driver is Conexant Smartaudio HD series, if you continue to look down; Second, in the headset itself is not defective, sound card driver normal and not mute, if the headset inserted or control speaker speakers, it is necessary to use the following met

() Mediarecorder instance. To start audio capture, call MediaRecorder.start() . To stop audio capture, call MediaRecorder.stop() . When you do with the Mediarecorder instance, call on MediaRecorder.release() it. Calling is always recommended to free the MediaRecorder.release() resource immediately. Call release is always the recommended way to release resources immediately Example:record

This article corresponds to the opening link of the previous "C ++ playing audio stream (PCM bare stream)". It describes how to use C ++ to implement the recording function. Similarly, you can directly create a win32 console program and copy the code to a file name to use it. You can also download the project you uploaded. This project was written in VS2013, if it is a lower version, it will be okay. Click

Added a frame image for Automatically Obtaining streaming media files and automatically generating images. The significance of this function is For example, if someone wants to see a movie, but does not want to take a long time to download the whole movie or clip. Therefore, the video is automatically captured.A picture is equivalent to a poster and an overview. Without a doubt, it takes much longer to download a picture than to download a movie clip! After seeing the "poster", the user de
