I got file recorded in Philips speechexec.
I've tried to edit header of this file to open it with different codec but I didn't succeeded. I used Philips CELP codec but I couldn't read it either.
I got information about that this file could be encrypted in SpeechExec transcription software but this application only work with Philips kit.
So is there any other way to decrypt this file?
There is no way you can decrypt this file as Philips is using a proprietary algorithm.

is there any better way to play Mp3 than mciSendString?
mciSendString sucks, and hard to use in muilti-thread, eg.hard to get the current PlayingState
I'd suggest DirectShow or Windows Media Foundation, since both have flexible APIs for file based playback (you won't have to deal with reading the file and understanding the format, looking up codecs etc.) and still expose playback control. See these articles:
DirectShow and IGraphBuilder (very simple and straightforward) - How To Play a File
How to Play Media Files with Media Foundation

I'm using Azure Media Services and I need to encode input audio files to mp3 output files. I've used Standart Encoder for encoding video files, but it seems Standart Encoder can't produce mp3 (I understand that it can encode audio with AAC and produce mp4 file with the audio but unfortunately I need exactly mp3).
So I'm trying to use Media Encoder Premium Workflow. In the documentation, I see that I need to use Workflow Designer tool but can't understand where I can get it. Could you please point me out where I can find it? Or maybe you can suggest other solution for getting mp3 after processing audio using Azure Media Services?
I see that you have considered Azure Functions. Since that does not appear to address your needs, please contact us via mepd#microsoft.com
We'll provide you the instructions on how to download the Workflow Designer, and use it.
I am looking to support playing DRM into custom player which is built using NDK C++ library as plugin which decodes, converts and then perform some image processing before final presentation. In this scenario, what is the best way to support DRM (I will use NDK's Crypto and DRM interfaces) given that documentation hints at only supporting MPEG-DASH format, which is not natively supported.
Clarify if any of my assumptions are incorrect or there are simple libraries (like libdash) which can solve the problem. Extreme solution in ExoPlayer but current infrastructure is built using C++ and NDK interface to leverage hardware decoders, which excludes that as an option.
If your image processing requires access to the raw image then unfortunately you won't (or you shouldn't!) be able to do this as encrypted video is designed to play via a secure media path which does not allow access to the raw video.
I am making a game where I want to command the AI using word i speak.
Say for example I can say go and AI bot goes to certain distance.
Question is I am finding asset and no provider is giving me grantee that it is possible ?
What are the difficulties for doing it?
I am programmer so if some one suggest the way to handle it I can do it.
Should I make mic listener on all the time and read audio and then pass audio to some external sdk which can convert my voice to text ?
these are the asset provider i have contacted.

and few more !
If someone just explains the steps I need to follow then I can try it for sure.
I am currently using this external api for pretty much the same thing: https://api.ai/
It comes with a unity SDK that works quite well:
https://github.com/api-ai/api-ai-unity-sample#apiai-unity-plugin
You have to connect a audio source to the sdk, and tell it to start listening. It will then convert your voice audio to text, and even detect pre-selected intentions from your voice audio / text.
You can find all steps on how to integrate the unity plugin in the api.ai Unity SDK documentation on github.
EDIT: It's free too btw :)
If you want to recognize offline without sending data to the server, you need to try this plugin:
https://github.com/dimixar/unity3DPocketSphinx-android-lib
It uses open source speech recognition engine CMUSphinx
Is it possible to implement a custom codec decoder and play a media file using JSR135? Actually I am interested in playing back a custom media file in J2ME. I think JSR135 is a good starting point but I am open to other suggestions. Thanks.
Update
I have not tried but I believe, if I open the file using JSR75 I will get an InputStream. I can use a custom InputStream that converts the custom codec to a known codec that MMAPI will understand and I can playback. However it would be better if I can do without using JSR75 and many security warnings that will come with it.
