I'm a complete newbie at Appcelerator's Titanium SDK, so I apologize in advance if this question has an obvious answer.
Is there any way to change a sound's pitch in real-time using appcelerator? Is there a module that can do that?
When looking for the answer, I found out about some objective-c libraries (dirac-2, for example) that can do that. Is there any way to interface to such libraries through Titanium without a dedicated module?
After some searching, I found a module - Zero Latency Sound - that can control a sample pitch in real time.

Also, this module's support is commendable.

over the past week or so I’ve been trying to find a workflow for original sample generation to eventually be used in an audiokit app, obviously at some point Im going to have to decide which of AudioKits sampler classes best fits my needs and I have a few
Questions about what I have found so far :
I won’t be getting Logic Pro anytime soon so I think EXS24 is not an option right now, as a side question - are there any other
Apps which can generate .esx24 files?
The MIDISampler in AudioKit has a method .loadSoundFont( - is there a documented example of this? (couldn’t find any in cookbook)
I was able to get this working with .sf2 files but I want to make sure Im doing it properly.
There is a Sampler class in DunneAudioKit - I was also able to establish a workflow in this using .sfz files - this seems pretty good
Currently I am deliberating between the MIDISampler in AudioKit and the Sampler in DunneAudioKit
Are there any other options in the audiokit framework(s) that I should consider? Also the file formats .sf2 and .sfz I am guessing are probably going to stay in use for some time - has anybody heard about either of those two being deprecated or changed in a major way?
GarageBand can make AUPreset files and MainStage can make EXS24 files suitable for AppleSampler. I've not tried the DunneSampler but I believe that is the one AudioKit Pro uses for several of their commercial apps. There isn't an example in the Cookbook for SF2 in AppleSampler but it should be very similar. SF2 has been around for a very long time and I imagine SFZ will be too.
I want to use C++ library which makes it easy to build high-performance audio apps

Google Oboe seems for Android
can i somehow use it for iOS also ? or any similar alternative for iOS ?
I don't want to use Superpowered because of their licence terms!
There are no plans to release an iOS version of Oboe at present. You could look at FMOD or JUCE.
If I remember correctly (from videos of demos at events), The development of this library came from people heavily involved with the Google Android infrastructure, and thus the Oboe library is highly customized to tackle the low-latency short-comings of Android.
This being said, Google would not have the resources to tackle such an intensive and complicated problem for a completely different platform. As well (unfortunately) that wouldn't be in their best interest competitively-speaking.
I have heard of others using Superpowered, but I haven't gotten much info on it honestly, their marketing about it is all fluff, and there isn't any actual useful information, haha. I used Oboe myself, because I needed a dedicated native library.
As for iOS, I found a decent blog page that might be worth checking out: https://exceed7.com/native-audio/
This page suggests using OpenAL for objective-C/Swift. It looks like OpenAL is the similar implementation to OpenSL, which the Oboe library is partially based on. Unity seems to also utilize a library called FMOD (Not familiar with this one myself), as well DonTurner mentioned JUCE?.
So perhaps looking into these would be a good start, although I would assume using OpenAL might have some pretty involved developing, so ready your thinking cap!
Best of luck on your project!
Maybe you are looking for AudioKit

I want to learn in reasonable depth iOS socket programing with SWIFT.
I tried:
Apple documentation - its written for C++ and is overcomplicated (I learned Java socket programing in a week, this has so many things that are unnecessary)
Searched the forums on Stack, but looks like everyone is doing something different with CF or NS libraries.
This resource: http://swiftrien.blogspot.com/2015/10/socket-programming-in-swift-part-2.html - simply for me its overcomplicated.
Ray Wenderlich in https://www.raywenderlich.com/3932/networking-tutorial-for-ios-how-to-create-a-socket-based-iphone-app-and-server - is again doing C++ and is using 3rd party
and so on...
Is there some holly grail that has simple syntax like in Java, or am I doomed to work with some C++ things in my Swift code?
Thanks in advance.
Try looking at https://github.com/IBM-Swift/BlueSocket. This a cross platform framework for doing socket level programming in Swift.
I highly recommend you to use a socket framework to start with.
SwiftDSSocket is a framework written in pure Swift and I actively maintain this framework. It has really simple API and documents available as well as Demo.
I want to get stream of an ip-cam on my iPhone/iPad and want to display it on screen. By R&D i found that ffmpeg is the only way to achieve it but i found nothing on ffmpeg. Is there any other way to achieve it or a confirmed way to get compiled ffmpeg on mac please mention that. Material regarding how to use ffmepg or source code example will be highly appreciated.
Is there nothing built-in framework to achieve it if not then please mention if there is any free framework/sdk to achieve this functionality.
Thanks
There are actually a few.
here are some links

I am sure if you google you can find more.
I cannot only address the first one, because that is ours, but I didn't want this to sound purely like self promotion.
I am not very familiar with Game engines for iOS app. Can anyone suggest an open source game engine for my game development?
My game scenario is as follows: The user selects a map, and a character inside of the game I moves through a path predefined in the map.
I was thinking about writing this game in OpenGL but it seems like I have to write a huge amount of code. Do any game engines exist in which I can successfully write this game?
Lua is easier to learn than Objective-C. There are several Lua development environments:
Gideros Studio: http://www.giderosmobile.com/
Corona SDK: http://www.coronalabs.com/
Moai: http://getmoai.com/
My favourite is Gideros Studio, because it seemed to me the easiest to get started, and is free until you want to remove the splash screen, and has a very friendly forum with access to the developers. You can also include native plugins (Objective C and C++ for Android).
Moai is the only actual open source one, if you really need to change the source, but it is probably the hardest one to learn.
cocos2d is popular and easy to use and learn. you could also use kobald2d as that includes cocos2d and other frameworks as well. you can download them through a search on google
As state by the other user cocos2d would be a good solution for what you want. Although you asked for "open source", you can always check, for free, Unity for iOS. You could also check a question I made some time ago, which can give you some hints of some options you have, here. From the Unity site:
Oh, and don't forget that Unity is free and we have fully-functional
30-day trials available for Unity Pro and Unity iOS Pro!
I know it's not perfect, but still, if you see it's worth, it can make a huge difference in your project.
Try Stencyl, it's not free, but it is a good engine that doesnt require a lot of code
