wav

问题 I must concat 2 or more audio (wav or mp3) files and get one audio file. How can I do that in android? Thanks in advance. 回答1: The below code section will work as how many selections have been made.Selection means how much files are selected. Put your two wav files in /sdcard0/SSoftAudioFiles/ as 1.wav and 2.wav. And Just execute this method. public void SSoftAudCombine() { try { String[] selection=new String[2]; selection[0]="1.wav"; selection[1]="2.wav"; DataOutputStream amplifyOutputStream

问题 I have 2 wav files that I want to concatenate into one file with the two sound tracks. Is there any api for that task or some built in commands in .NET that can I can use in some genius way to make this task possible? Many thanks for the help. :) 回答1: If I'm not mistaken, you can just append the bytes from the second file to the end of the first. If there is any header data, you'll want to exclude that (see here) Be advised that you may hear a click or pop between the two clips, as there will

问题 By looking into another SIPp related question I learned that it is now possible to play WAV files using the rtp_stream action. I've tried several different WAV files with no success. All I get is some noise instead of the expected sound. In one comment in the mentioned question there is a simple instruction to convert a WAV file to a compatible format but it didn't work as well. I've also tried to use sox to convert this file with no success. Can anyone instruct me on how to generate a valid

问题 I am currently developing a website using the CodeIgniter framework and in one of the Process I need to download a .wav music file and convert it to .mp3 file. All the coding needs to be done only in PHP and I cannot use Ruby or java to do so. And I am currently hosting on a shared env i.e. Dreamhost. So please let me know how to work out this problem. 回答1: Use FFMPEG. There is a PHP extension for it, but I've found better success just calling exec() . Most hosts I have used (even shared

问题 I have a very huge WAV file, about 100MB in size. I would like to use Java to read this wav file and split it into smaller chunks for every 2 seconds of audio. Is it possible to do this in Java? Could you please suggest me an API with which I can achieve it? Thanks in advance, Snehal 回答1: You can use AudioInputStream and its AudioFileFormat member (which contains an AudioFormat instance) to know what to write (format, sample rate), you can use AudioSystem to write it. Based on the sample rate

问题 I'm trying to write a SAMPLER program, where each key has a different sound (a WAV file). Can someone explain to me or give me a link to an explanation where i can learn how to play the WAV files? If it matters, I'm working with Microsoft Visual C# and using WinForms. 回答1: SoundPlayer simpleSound = new SoundPlayer(strAudioFilePath); simpleSound.Play(); 回答2: use fmod, which is simply the best sound library in the whole universe fortunately, they seem to provide a C# wrapper for the best audio

问题 I want to make a program in assembly/8086/masm/dosbox that turns the keyboard into various musical instruments so i need to be able to play some .wav files to produce the required sounds.I am aware of beep char and producing sound via sending frequencies to pc speaker (ports 41h,42h and 61h) but both ways are clearly not going to get me there. I searched around and found that I need to use int 21h for opening files, knowledge of .wav format and knowledge of sound programming using Sound

问题 I'm looking for a C# source code that performs a frequency analysis on a WAV file and displays the results in a graph, similar to the one displayed in apps like WavePad. Do you know where I can find such a code? Thanks! 回答1: It's in a very experimental state at the moment, but if you have a look at the WPFDemo project in NAudio, it performs an FFT on the incoming microphone data or sound file you play and plots it under the wave-form. 来源： https://stackoverflow.com/questions/1377661/frequency

问题 I'm trying to get the data from a wav file in Python and plot it. When I use scipy.io.wavfile.read(), I get back an array that looks like this: [[ -1.49836736e-02 -1.27559584e-02] [ -1.84625713e-02 -1.63264061e-02] [ -2.17888858e-02 -1.95001373e-02] ..., [ 6.10332937e-05 6.10332937e-05] [ -3.05166468e-05 0.00000000e+00] [ 3.05166468e-05 -6.10332937e-05]] Why is it a bunch of arrays with length 2 as opposed to one long array with the value at each sample? What does this data being returned
