Hi
I have reviewed your project description and have understood your requirements.
I have assumed that:
1. The solution for recording to be used, will be some free/opensource available on Internet.
2. Once the recording will be done, it would be uploaded on SoundCloud in one single file format.
3. We don't need to display the file anywhere or need to develop player to play the file on the website.
4. A record/play player will be developed at the time of recording.
5. No media server will be used.
If you feel interested, we can discuss further.
Kind Regards
Sam
