问题 Using C# and NAudio, I have have three wave files I would like to join into a single wave file having three channels, each corresponding to one of the three input files. Furthermore, I would like the audio clip from each wave file to begin at a different point in the final stream. For example, if the lengths of the three wave files are 3 sec., 5 sec. and 2 sec., respectively, the output wave file would be 10 seconds long and... channel 1 contains the 3 seconds of sound from file 1 followed by

I'm wanting to create a program that you can import an mp3 file into, and tell it to play it starting at a specific position, and to play for a specified amount of time.

If you're using NAudio, look for a Seek method on the output stream -- the information returned from this Google search, http://www.google.com/search?q=seek+site:naudio.codeplex.com , should get you started. You could also use some old but functional Windows APIs (the MCI

问题 I'm new to NAudio c# but I am currently able to load an audio file and play it in my program. Now, I want to achieve being able to loop this audio file but not until after every 2 second interval. How can I achieve this? 回答1: For an accurate 2 second wait, I'd create my own IWaveProvider that in the Read method, read from your source file, then when it finished, returned 2 seconds of silence, and then started reading from the start of the source file again. For a rough solution, you can just

问题 I an trying to develop a windows application using C# that can play streamed audio data. Basically, I will have a client application that is responsible for playing different audio files. Currently, from the client application, I am extracting the hardware config param from the file header and then will stream the file data (PCM stream) over network. So is it possible to use the hardware config params sent from client to configure the actual hardware (on the server end) and then give it the
