1. Compile libmad 1. Download the compressed package to your local computer and decompress it. Tar-xvzf libmad-0.15.1b.tar.gz.-C ./ 2. Go to the source code folder and configure Compile a configuration file to facilitate . /Configure cc = arm-Linux-GCC -- Host = arm-Linux -- Build = i686-pc-linux-gnu -- enable-FPM = arm -- enable-shared -- disable-debugging -- prefix =/home/Tang /WiFi-music/mplayer/libmad-0.15.1b_install Run configuration and record information 3. Make compilation and recor

The first three articles have explained in detail how to convert the WAV audio format to the FLV format. This article describes how to convert the last part, first, the AMR is converted into WAV format, and then the WAV format is encapsulated FLV format. The key part of this article is the part in the while loop. The other part can be skipped. The function d_if_d

Because you only need to execute it on Windows, first think about using the MCI interface. After a try, mcisendcommand can be used to play the basic WAV file. However, loop playback of Wav is troublesome. The message mm_mcinotify must be sent to the window. After Google, we found that there was a simpler method-UseSndplaysound. One statement, sndplaysound (filename, snd_async | snd_loop), can play audio f

Find the uda1341 driver on the internet, compile it into the uda1341.ko module, and open the Kernel configuration menu.Device Drivers --->Sound --->Make modules generates the soundcore. Ko module. Load the two modules to play the audio. After carefully reading the uda1341 driver, we found that only 16 bits of audio can be played.Convert to dual-channel when copying to the driver. Therefore, we recommend that you select 16-bit dual-channel WAV audio.Fi

PCM (pulse codemodulation----Pulse Code modulated recording). The so-called PCM recording is the sound and other analog signals into the symbolic pulse column, and then recorded. PCM signal is a digital signal composed of [1], [0] and other symbols, without any coding and compression processing. Compared with analog signal, it is not susceptible to the clutter and distortion of the transmission system. The dynamic range is wide and the effect of sound quality can be very good.

What is a WAV file.The WAV file directly reflects the size of a sound at each time point, for example, the following waveform:Take one point for 0.1 seconds each person. The obtained WAV file value is 0, 1,-, 1. Therefore, if we can directly add the data of many wav files, you will hear all the sounds, which is the pri

Wav TO amr and easy adjustment of the volume, wavamr volume Let's talk about how to convert wav to amr. Wav is the easiest way to generate recording audio on PC, but the disadvantage is that the generated audio volume is relatively large. Amr is a mainstream audio playing format on mobile phones. Its advantage is that the audio is small in size and easy to transm

Ask for help: My job requirement is to generate a waveform diagram of a MP3 file. My idea is to first generate a WAV file MP3, and then use the WAV file to generate a waveform diagram. All the process will not, ask for help. Originally, I want to exec (lame ...) This converts the MP3 into WAV, but finds that sometimes the conversion fails. Later, some experts

This design idea: first open a normal WAV audio file, from the 44 bytes in front of the defined file header, remove the file header definition message, placed in a file header structure. Then open the ALSA audio driver, from the file header structure to remove the sampling accuracy, the number of channels, sampling frequency three important parameters, using the ALSA audio-driven API set parameters, finally open the

Python uses wxPython to open and play wav files, This example describes how to use wxPython to open and play wav files. Share it with you for your reference. The specific implementation method is as follows: ''' wx_lib_filebrowsebutton_sound.pyselect a sound file and play itwx.lib.filebrowsebutton.FileBrowseButton(parent, labelText, fileMask)(combines wx.TextCtrl and wxFileDialog widgets)wx.Sound(fileName,

This article mainly introduces how to use wxPython to open and play wav files. it involves python-related techniques for operating audio files, for more information about how to use wxPython to open and play wav files, see the example in this article.
