audio-streaming

问题 (This is a follow-up question to this one.) I want to read an endless audio stream asynchronously, so that I can do my JIT analysis on the obtained data. Using a WebClient object's DownloadDataAsync method, I can initiate the download easily, see following Win form project: Imports System.Net 'For WebClient Public Class Form1 Private WithEvents c As New WebClient() Protected Overrides Sub Finalize() c.Dispose() MyBase.Finalize() End Sub Private Sub Form1_Load(sender As Object, e As EventArgs)

问题 I'm playing aac audio stream on my iOS device using GStreamer SDK, its working fine, but delay is above 2.0 seconds. Can I make this delay lower then 2.0 seconds? There may be some buffering issue. This is how I'm creating the pipeline pipeline = gst_parse_launch("playbin2", &error); 回答1: try setting the latency like this: g_object_set(G_OBJECT(pipeline.source), "latency", 250, NULL); 来源： https://stackoverflow.com/questions/32865653/gstreamer-aac-audio-stream-delay-in-ios

问题 I have an ASIO device (Presonus Firestudio 2626). I am using it to mix and create different outputs on all of it's provided outputs (about 9 outputs like ADT1, ADT2). I need someway to stream these outputs using either IceCast or FFMpeg RTP. One of the problems is that I have a restriction on using only a MAC or a Windows machine as my ASIO device does not provide drivers for ubuntu. What are the ways that I can connect the ASIO device outputs to IceCast or FFMpeg? I've tried the following.

问题 I am developing a new UWP app which should monitor sound and fire a event for each sudden sound blow ( something like gun fire or clap ). It needs to enable default Audio Input and monitor live audio. Set audio sensitivity for identifying environment noise and recognizing clap/gun-fire When there is a high frequency sound like a clap/gun-fire sound ( Ideally it should be like configured frequency like +/-40 then it is a gun-fire/clap ) then it should call a event. No need to save Audio I

I did some research for possible solutions and also tried audio streaming via HTTP URL, but it was not feasible and also involves internet. I'm looking for your opinions and if it's doable then what is the right approach, (what libraries and API's should I look

What should be the format ? 回答1: The metadata is not required for a stream to function. If your data is corrupt, you are either encoding it wrong or are sending the wrong Content-Type header. That being
