For a project I'm working on, I need to produce approx 5000 voice-only recordings of approx 15 seconds each (typically each file is a couple of short sentences spoken aloud). I've approached this as follows (I'm using Adobe Soundbooth for all the steps below):
- I make the recordings in as few takes as possible.
- I then fix up each of these files, normalising them and applying noise reduction (specifically, I use the "Clean up audio" function and "Advanced Dynamics" which seem to give a nice, clear result)
- I then cut the recordings into the individual files (which takes forever)
At this point I find that there can be quite large variances in the volume between the individual files so I use the "Volume Correction" task in Soundbooth to match them all to a reference file.
The issue is that, even after doing this there can be some files that are way off. So as a further job, I go through every file making manual volume correction. This takes a LONG time, longer still because there's only so much of it I can do in one sitting without losing the plot. So it's this last step that I really want to avoid. I don't want to skimp on the quality - I need to ensure that each file is very closely matched in terms of perceived volume - but I would really like to find a reliable way to automate this.
Can anyone help?
Thanks in advance for any guidance you can give.
P.S. I'm open to considering other software (than Soundbooth) if it will cut out any of the manual labour of producing these files.
