问题 I want to export a double[] array to a wav file. I'm having some trouble manipulating the headers (RIFF, fmt, etc) . Any ideas how I should approach this? Maybe use BitConverter to turn the double[] array into a byte[] array and then use NAudio's waveFileWriter? Any sample code much appreciated! 回答1: Just use WaveFileWriter's WriteSample method to write each sample one by one, or WriteSamples to do it in one hit. Since you have an array of doubles, you can use a bit of LINQ to convert to a

问题 I've got a small Maven Java project which requires the playing of a WAV file, and so I'd prefer to simply put the file into the src/main/resources/* folder for simplicity. However, if the same WAV file which works fine being loaded from disk using AudioSystem.getAudioInputStream(...) is then put in the Maven resources directory, the program throws an instance of RIFFInvalidDataException: com.sun.media.sound.RIFFInvalidDataException: Chunk size too big at com.sun.media.sound.RIFFReader.<init>

问题 I'm trying to create a loop for reading in stereo wave files in R, but I'm unsure if I should use for.loop or while.loop. I'm calculating the RMS for both channels. Here's the action for one sound file: foo=readWave("mysound.wav") L=foo@left R=foo@right rms(L) rms(R) Now, I have directories full of 2 minute sound files. I want to take each of those files, isolate the channels, and calculate the RMS. I THINK this is how it's done: mydir=list.files("directory", recursive=TRUE) for (i in 1

问题 I am new learner of audio editing libs - Pydub. I want to change some audio files' playback speed using Pydub(say .wav/mp3 format files), but I don't know how to make it.

Could anyone kindly explain how to do this task in Pydub? Many thanks! (A related question: Pydub - How to change frame rate without changing playback speed,
