Will Realitykit support an ambisonic recording? I am planning on using binaural audio in an AR experience but it looks as if RealityKit doesnt support it. Looking for help.
At the moment RealityKit 2.0 doesn't support Ambisonics. It's hard to say whether it'll support it.

I want to make an application that counts the speaking time of each speaker in an audio recording. I don't care about doing full voice recognition and transcribing every word in the recording, I just want the speaking time of each voice.
Is there a piece of software that provides such feature?
If possible, I would like to avoid using a third-party service (such as Google Cloud) to achieve this, and I would like the solution to be light enough to run on a modern smartphone.
Thank you for your help.
I had the same idea. Check this out https://github.com/pyannote/pyannote-audio
Haven't tried it myself yet. Will add an edit after.
Is here any audio Library or Framework to use with Swift 2.x. I am looking for something which can handle the Live Stream Buffering or latency. I am using AVAudio Player for Live stream but it is not an excellent choice. I don't know the objective c , so its hard for me to get reference to those docs.
Please suggest. Thanks in advance.
Here is the one of the best library which is purely written in swift.
Jukebox
However, you can still use AVPLayer. It's the one and the same thing.
I am looking for an audio dsp library for cleaning up some speech (voice) recording. I have not decided which language to use yet.
Here are the feature I am looking for:
Work in Linux and Windows
Importing MP3
Working with multiple channels mixing
Noise Filter
Bandpass filter
Compressor
I love to have these as well, but I can write my own if they are not available:
De-esser
multi-band compressor
Expender
Envelopes
(if you can suggest an application that do these in scripting / one mouse click, I will accept your answer too)
What about something like SoX?? http://sox.sourceforge.net/
Take a look at Juce from Raw Material Software.
It is free for non-commercial use, and very reasonably priced for commercial use. it also has a lot of built in audio capabilities (mixing, file I/O, etc.) and has a nice cross platform GUI toolkit as well.
Audacity does most of those things.
I am trying to make an application for listening to podcasts. Each podcast is an mp3 file, around 50MB in size. After reviewing the Using Audio chapter of the Multimedia Programming Guide, I decided to use AVPlayer, as the other options did not seem appropriate. However, the more I work with AVFoundation, the more complicated it seems and I have a feeling that simply streaming an mp3 file should be easier. Plus on the top of this document, there is a note stating:
Important: This document contains
information that used to be in iOS
Application Programming Guide. The
information in this document has not
been updated specifically for iOS 4.0
Does that mean that I have some other options, or that AVFoundation is maybe an overkill for what I need to do? I would really appreciate it if someone could clear things out a bit and let me know if I'm making something wrong here.
Thanks in advance!
You should explore Cocos Denshion.
http://www.cocos2d-iphone.org/wiki/doku.php/cocosdenshion:cookbook
The audio engine comes with cocos2d, and it is just 5 classes you can include with your project.
It's very simple to use, as you can see from the above link. It's basically just a wrapper for some AVFoundation classes.
The only trick will be to stream your mp3, but it looks like you can simply update the Cocos Denshion CDAudioManager to hand a URL to the AVAudioPlayer, as a start. Whether or not that satisfies your streaming requirement, I don't know.
At the very least, it will give you some AVFoundation code to study.
I just found a pdf with a nice overview of some possible options from this course blog. Together with Julian's suggestion this is all I could find so far.
I'm looking for something like paint.net or Gimp, but for audio files, and runs on windows.
Audacity is fantastic
As already mentioned, Audacity is fantastic. If you're looking to batch convert sound files at the command line, check out mencoder and (for MP3s only) LAME.
Audacity is painfully limited. If you are looking to do something a little more complicated. You should check out Reaper. It has a 60 day free trial and if you are still doing editing and recording after that long, the price to buy is extremely cheap when compared to other fully functional editing software. Pro Tools is crazy expensive.
Personally I use REAPER for "complex" tasks (tracking, mastering, batch processing) and Audacity for basic cutting/normalizing/exporting to MP3.
If you need free alternative for Audacity for basic mono or stereo file processing, you may try Wavosaur or other software that has realtime previews.
NCH Wavepad is also the best application for the audio. it's easy to understand
Reaper has always worked very well for me. It is free to download and try for 60 days and requires a cheap license after that (there are two different price options). Highly recommended.
