Bluetooth recording app

Looking for a developer that can code in IOS and Android environments. The ideal Developer will have experience working with Bluetooth audio and writing audio recording applications for these two platforms. We need to record the transmission of wireless Bluetooth audio from our custom Bluetooth device on to phones and tablets then upload those recorded files to our website or email the file to any recipient. Specific features: We need an auto gain function on the input of the recorder to adjust the incoming levels automatically. We also need an auto pause feature for when there is dead air. Reducing the recording length when no sounds are heard from the device. Using a volume threshold adjustment to trigger the auto pause feature when volume drops below this threshold. The recording will then continue when the sound gets above this threshold. The sample rate and bit rate can be rather low. We certainly don't need 96k sampling rates as these will be speech recordings. User interface: The IOS and android versions should be identical in appearance and should function in very similar manner. The user interface should be very easy to use with all the recording functions hidden behind the scenes. Something as basic as a record button on screen that changes to a Stop button when the recording begins. After the recording is stopped an option menu is displayed to Discard, Email or upload the file to our website. After one of these options have been chosen and successfully implemented the recording is erased from the device and ready for a new recording. If you feel you have the expertise to create this app we would love to hear from you.
