audio-streaming

问题 Using VB.NET, I want to analyze input audio streams obtained from Web radio stations (e.g.: "Flower Power Radio" via TuneIn). However, I am struggling in finding a suitable starting point. Obviously, when entering into the Web browser a Web address (as given in above example), a stream starts flowing and is being interpreted by, in this case, said Web browser. Only that my planned experiments do not involve the requirement for a browser; and since I do not want to replay the received audio

So, I decided to try PyAudio, but I can't figure out how to stream an mp3 source from HTTP with it. All the examples are wav files and I need examples rather than the docs or I'm afraid I'll have to figure out the particulars of how audio works on the lowest

问题 In the following example what I'm trying to do is initialize a unique stream for each client that connects to the server and serve that stream to the client through html5's audio tag. Because I want a live experience I'm attempting to write the latest buffer from my transcoding to the output of the audio stream. For testing purposes I'm grabbing NPRs public stream, transcoding it via transcode.sh to speex, and serving it to my clients. The issue is that when I connect, the transcoded stream

问题 We are facing problem to draw the audio visualization (graph) by wavesurfer JS in Firefox for some specific format of the mp3 file. It always gives us the error like: The buffer passed to decodeAudioData contains an unknown content type. But same file is running in chrome without any problem. After the investigation, we have found that decodeAudioData() is used in wavesurfer JS which is generating the error while decoding audio file data contained in an ArrayBuffer. Since we don't have an

问题 I would like to include an audio/possible video player on my website with the following attributes: Must be placeable via a <div> ; Styled via CSS; Can read all ID3 info; Can pull the file from a database (probably GoDaddy's Easy Database); No flash; Transferrable to smartphones etc. I have been herded to SoundManager2 which appears to fit the bill, but I seem to be having real trouble just making a clickable image to begin playing my mp3. I have zero JS skills so am going from silly basic

问题 I am studying C# by myself by reading some books and watching some tutorials. So, i decided to make a small project at the same time, to get more experience and harden my knowledge. I am trying to create a text to speech program in Georgian(my language).
