Audio Recoding demo app

Hello, We need a sample/demo application - no need to upload to store or anything just a sample app to prove something is working. (The source code) Specifications: There is no design, this is just a Proof of Concept. We would like minimal UI, (1 screen) able to see recording has started, recording time, recording has stopped.(buttons for recording/playing/loading raw samples files, listView displaying the files loaded, normal textView for recording time) App Requirements: - Able to record audio and save as raw samples files - separated functions for both PCM16 & PCM8 recording (dedicated buttons for actions) - Able to load raw sample files (for both formats) and play them one after the other as if the actual and original recording was playing (dedicated button for action) - Able to save raw samples to a specific folder which can then be open by app and read from (play the selected files) - Able to convert raw samples into an audio file (dedicated function for loading the raw files and converting them into an audio file) - Recording Quality changer (Basic, Medium, High, Superior) - easy settings button, no need for any UI complications - Recording Mode (Stereo & Mono) if possible So for conclusion we would like a very simple application to prove it meets our requirements and to be able to play raw files and the other mentioned specifications. Please make sure all functions are fully documented with proper API for faster understanding of the code. Please feel free to contact us if something is not understood. Pricing can be discussed P.s. this demo application will open future work as well with bigger budget. Regards, Asid-Apps
