wav

OK, so I'm trying to make a program that will manipulate .wav files, and I've seen this question/answers , but I'm not entirely sure as to what each piece of data in the header refers to. For example, what does a "chunk" refer to? Is that a specific number of bits/bytes? If somebody could just tell me, at least in the format used in this question, what each datum being written to the .wav, aside from the constant String Literals and the 'data' array, refer to? In particular I'd especially like to know what a "chunk" is, and how Sample Rate, Byte Rate, Bytes per Sample, and Bytes per Sample for

I know about the clip.stop() method, however it doesn't seem to work within when I have it inside the key_events. It just causes an Error. Well I know why it causes the error. Because I'm asking it to essentially stop a clip that doesn't exist until a few lines later. But using this same logic or close to it if possible, how could I recode that so it knows to select the previous clip that was playing from a previous key_event. The functionality I'm intending for is: When F1 is pressed, a wav plays. When F2 is pressed, current wav STOPS, new wav STARTS. When F3 is pressed, current wav STOPS,

I'm in a very early stage of writing a small music/rhythm game in Java (via Slick framework, which in turns uses OpenAL, but that's probably irrelevant here). The game needs to read (and playback) several sound files in WAV format, but some of the files are throwing [javax.sound.sampled.UnsupportedAudioFileException] exceptions. at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1102) at org.newdawn.slick.openal.WaveData.create(WaveData.java:123) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:713) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java

This may sounds little odd or question may be a trivial one, but for most of my life I was programming in PHP (yeah, I know how it sounds). So when I switched to C++ there are things quite unfamilliar for me (cause of php habits). So I'm loading wav header data using struct. Values are definded as uint8_t type: typedef struct WAV_HEADER { uint8_t RIFF[4]; // RIFF uint8_t WAVE[4]; // WAVE } I have to compare them with four-letter strings for something like that: if(wavHeader.RIFF[0] . wavHeader.RIFF[1] . wavHeader.RIFF[2] . wavHeader.RIFF[3] == 'RIFF') { do sth } This should be easy check if

I need to read data in from a wav file in 24 bit pcm format, and convert to float. I'm using Python 2.7.2. The wave package reads the data in as a string, so what I've tried is: import wave import numpy as np import array import struct f = wave.open('filename.wav') # read in entire wav file wdata = f.readframes(nFrames) f.close() # unpack into signed integers and convert to float data = array.array('f') for i in range(0,nFrames*3,3): data.append(float(struct.unpack('<i', '\x00'+ wdata[i:i+3])[0])) # normalize sample values data = np.array(data) data = data / 0x800000 This is quite a bit faster

I am trying to play a sound with QSound module. It try with this code and works: QSound::play(":/sounds/sources/BeepSound.wav"); But I want this and doesn't work: I create a dynamic instance of QSound and played: sounds = new QSound(":/sounds/sources/BeepSound.wav"); sounds->setLoops(3); sounds->play(); Any tips? Update I don't want to use others modules like QMediaPlayer , QAudioOutput because I want something really simple, just play a sound. 来源： https://stackoverflow.com/questions/30812327/qsoundplaysoundpath-call-works-but-a-qsound-object-doesnt

The following code works with some wav files, but with others I get, "InvalidOperationException was unhandled. Message=Sound API only supports playing PCM wave files." var webClient = new WebClient(); webClient.DownloadFile(url, fileName); var fileSound = new SoundPlayer(fileName); fileSound.PlaySync(); Is there a way to programmatically check if a wav file is "bad" (not a PCM wave file) and then convert it as necessary? What is odd is that the code works in the legacy Delphi app - all of the wav files play just fine. Here's the Delphi code: filename := GetEnvironmentVariable('TEMP')+'
