How to record and playback with NAudio using AsioOut

由 十年热恋 提交于 2019-11-28 00:36:43
I'm trying to get the sound input and send output directly with less latency possible with C#. I'm using the library NAudio that supports ASIO for better latency. In particular, I use the AsioOut object for recording and another for playback initialized with a BufferedWaveProvider , which is filled in a Callback function: OnAudioAvailable , which allows me to use the ASIO buffers. The problem is that I hear the sound with various glitches and with a bit of delay . I think the problem is in the function OnAudioAvailable where the buffer is filled with data taken as input from the sound card.

I'm having some issues with naudio and saving sound recordings. The code I currently have works to the point where it saves the wav file, but when I open it up, Windows Media Player returns an error: "Windows Media Player encountered a problem while playing the file" I have two buttons, a "Record" button, which turns into the stop button after it's pressed. And I have a "Save" button which when clicked, saves the recording to sample.wav . NAudio.Wave.WaveIn sourceStream = null; NAudio.Wave.DirectSoundOut waveOut = null; NAudio.Wave.WaveFileWriter waveWriter = null; private void recordButton

Using NAudio to decode mu-law audio

问题 I'm attempting to use NAudio to decode mu-law encoded audio into pcm audio. My service is POSTed the raw mu-law encoded audio bytes and I'm getting an error from NAudio that the data does not have a RIFF header. Do I need to add this somehow? The code I'm using is: WaveFileReader reader = new WaveFileReader(tmpMemStream); using (WaveStream convertedStream = WaveFormatConversionStream.CreatePcmStream(reader)) { WaveFileWriter.CreateWaveFile(recordingsPath + "/" + outputFileName,

问题 I am trying to use the NAudio.Lame library in an MVC4 application and am getting the error: Unable to load DLL 'libmp3lame.32.dll': The specified module could not be found.

问题 I have a program that takes in mp3 data in a byte array. It has to convert that mp3 data into wav format and store it in a byte data. I am trying to use NAudio for this purpose. I am using the following code for this purpose. Stream inputStream = ...; Stream outputStream = ...; using (WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(new Mp3FileReader(inputStream))) using (WaveFileWriter waveFileWriter = new WaveFileWriter(outputStream, waveStream.WaveFormat)) { byte[] bytes

NAudio to split mp3 file

由 余生长醉 提交于 2019-11-27 03:20:43
问题 I am very new to audio or mp3 stuff, was looking for a way to have a feature to split an mp3 file in C#, asp.net. After googling for a good 3-day without much of a great help, I am hoping that somebody here can point me to a right direction. Can I use NAudio to accomplish this? Is there any sample code for that? Thanks in advance. 回答1: An MP3 File is made up of a sequence of MP3 frames (plus often ID3 tags on the beginning and end). The cleanest way to split an MP3 file then is to copy a
