I have recorded an array[1024] of data from my mic on my Android phone, passed it through a1D forward DFT of the real data (setting a further 1024 bits to 0). I saved the array to a text file, and rep
I am having trouble understanding how I should pass PCM data from the mic to this FFT class I am using made by Piotr Wendykier (it\'s the DoubleFFT_1D class in JTransforms).
I\'ve been playing with this now for sometime, I cant work out what I am meant to be doing here. I am reading in PCM audio data into an audioData array:
I have an array of audio data I am passing to a reader: recorder.read(audioData,0,bufferSize); The instantiation is as follows:
I am creating PCM data (from sine waves) and piping them to the speakers using AudioTrack. I\'d like to record this as a wav file (or a comparable format). I\'ve looked at AudioRecord but it takes a
When I play a file with the following code: private void PlayAudioFileViaAudioTrack(int ResId) throws IOException {
Hi I need to read SampleRate,开发者_C百科 SignalFrequency and Amplitude from .wave file. How can I do that using JavaSound?You can get the sampling rate by getting a handle on the AudioFormat object:
Is there a way to use QtMultimedia to access the PCM raw audio samples of MP3 files stored on a, say, Nokia N950 phone?
I was following this tutorial on how to make a Silverlight audio recorder. I thought it would be great to add a volume bar indicator to provide user with a feedback on what\'s happening. However, I ca
I want to achieve PCMU fade out effect of the a开发者_开发问答udio. Lets say I have two pieces of 160 bytes of audio which correspond to 20ms audio duration each and I want to insert some silence betw
