Hi,
We are looking at writing a multi-channel (1-4) audio recording
application for court recording and transcription purposes.
We are looking to identify which technology to use: Quicktime or Core
Audio? The development team is Java based and we could either use
Swing or Cocoa-Java.
This application (which is for use on MacOS X) needs to have the
following features:
* Real time audio recording (1-4 channels) with a small control panel
showing VU meters and allowing the gain to be adjusted for each
channel independly.
* All audio must be time stamped in some way such that you can go to
point hh:mm:ss.s on playback.
* A facility to create time-stamped annotations (which later serve as
the hotlinks back into the audio for playback).
* The ability to attach any type of file with a time stamp.
* A facility to split the resulting audio and annotations and
attachments into segments (which say a 10 sec overlap at each end)
for uploading to a management app. These segments can then be sent
to different transcribers for verbatim transcription.
Does anyone have a view as to which is the best technology and the
level of effort for such an application?
Thanks,
Karl
