Answered 2018-Jun-12 at 06:39Please try to use the AVAudioSessionCategoryPlayback instead of AVAudioSessionCategoryAmbient.
AVAudioSessionCategoryAmbient : Use this category for background sounds such as rain, car engine noise, etc.
Mixes with other music.

QUESTION
I am trying to run my application which uses cscore (https://github.com/filoe/cscore) and its sub namespace "CSCore.Ffmpeg"
I've already tried what the author explained in "https://github.com/filoe/cscore/blob/master/CSCore.Ffmpeg/Readme.md" ('LD_LIBRARY_PATH=./ mono MyApp.exe') without success.
My question would be how to get it working on Debian 9 using mono. Additionally i would be grateful if anyone could tell me where i could get the required libraries for my operating system.
This is the stacktrace:
...ANSWER
Answered 2018-Jan-03 at 04:00Ok. Solved issue by installing the appropriate linux packages and copying the libraries from '/usr/lib/x86_64-linux-gnu/' into the folder where the application is.
After that i had to look what mono expects by setting the mono loglevel to debug (LD_LIBRARY_PATH=./ MONO_LOG_LEVEL=debug mono MyApp.exe) An error appeared (something like Mono: DllImport error loading library '/root/bot/Debug/libavutil-55.so': '/root/bot/Debug/libavutil-55.so: cannot open shared object file: No such file or directory'. )
Then i renamed the existing libavutil.so.55 to libavutil-55.so,I repeated that for every missing include and mono accepted that. I hope that helps everyone who has a similar problem in future.

I'm very new to Python and I was trying to use a nice library (audiotools) to play an mp3 playlist, just as an exercise.
This is the class to play the tracklist (loosely based on THIS, once I discovered there is a "callback function with no arguments which is called by the player when the current track is finished" (*) ):

I'm currently reading Chris Adamson's "Learning Core Audio" and try to follow along in Swift 3 (instead of Objective-C).
The first code example makes use of AudioTool to gather information about an audio-file. My Swift 3 version looks like this:
ANSWER
Answered 2017-Mar-02 at 00:15Swift's CFDictionary isn't itself a data structure; it's a pointer to a data structure, and it is equivalent to Objective-C's CFDictionaryRef. In other words, it behaves like a Swift class, not a struct.
The value written into outDataPointer is not a pointer to a CFDictionary; it is a CFDictionary. You're dereferencing it one too many times, causing the data stored in the dictionary to be treated as a pointer to a dictionary. On my system, the resulting memory address was 0x001dffffc892e2f1, which Objective-C treats as a tagged pointer, resulting in the NSAtom message.
To fix the problem, declare outDataPointer as a CFDictionary? instead of an UnsafePointer?:

I am new to kur and just trying it out.
with kur -v train speech.yml, it runs fine but with some annoying messages: 1. The tensorflow is not compiling SSE instructions; 2. system library 'libmagic' can't be found.
Should I worry about these? should I do something about these?
Thanks a lot! @AdamSypniewski where is the best place to ask questions about kur?

ANSWER
Answered 2017-Feb-28 at 17:00The "TensorFlow library wasn't compiled" warning is just a warning (c.f., this answer). Every thing will still work fine, but it is possible that you'll get a boost in performance if you compile/install TensorFlow from source, rather than from pip/conda. That's all.
The "libmagic" warning can (probably) be ignored as well. "libmagic" is the name of a library which uses magic numbers to determine the file type of an arbitrary file. Current versions of macOS don't have it installed by default, so Kur falls back onto its own file-format heuristic. If you aren't seeing errors and if your model output seems reasonable, you're probably fine. If you want to be super-careful, you can use a macOS package manager to install it; for example, using Homebrew, the command is brew install libmagic.
And since you asked, the best place to ask questions about Kur is on Gitter.
QUESTION
I need to record audio in an Android application that needs to be imported into Python (ndarray) for plotting and signal processing. It seemed like such a simple idea.
I started with a simple bit of code for AAC/MPEG4 recording. Recording worked great. I can play it on the Android phone (Nexus 5X) and on a Mac (Quicktime). No problem! Right?!? But finding codec/formats that match between Android and Python seems to not be trivial. I'm wondering if the file/codec format written by Android is non-standard and FFMPEG can't read it.
If so, what is good audio format/codec that can be written simply in Android and read into an array in Python (2.7.x). Thanks.
Details: Here is an abbreviated form of the android code:
