问题 I'm attempting to use the AudioGraph API of UWP to reproduce a mix of synthesised speech and short notification sounds ("earcons"). UWP has a speech synthesis API which gives me a stream containing a WAV file, but I don't want to make too many assumptions about the parameters (bit rate, sample depth, etc.) so the idea is to have an AudioSubmixNode and add AudioFrameInputNode s whenever there's some speech to reproduce. There's some complexity around queueing up separate utterances so that

问题 My app synthesises audio from a lookup table. It plays audio successfully but crashes the moment I try to stop playing. Audio playback only needs to exit without restarting so the requirements for handling the interruption are basic. I reread Apple’s Audio Session Programming Guide including the section Responding to Interruptions. However the method handleAudioSessionInterruption does not seem to register an interrupt so I’m obviously missing something. EDIT See my answer. When I began work

问题 I'm trying to write a simple music player using GStreamer. I want to play any arbitrary music file ABS_FILE_PATH , store the samples for other purposes and later loop over these indefinitely, once the original end of stream is reached. Now playing the music works fine until short after the last sample of the track was played. Most of the time there's just silence, but sometimes there are one or two audible samples indicating, that the track just started playing again. The same holds for the

My app decides which song to play when, but I don't want to write a full-blown music player app. I just want to feed the existing player app with new music. I am looking for something like "inter-app" communication (perhaps using Intent?) through which I can feed

问题 I have a shoutcat radio station and now want to build a player for it. I know how to "get" thet stream from the server, thanks a lot to bobince , but I am not sure how to convert that stream into playable samples. How is it done? 回答1: Well, from what I can read on python, try this page. If that doesn't work, try the PythonInMusic article on the python wiki. 回答2: Shoutcast streams are typically (but not always) MP3. To get playable samples, you have to decode the stream's MP3 data.
