Cool Edit Pro, from original live concert recordings

How to get the best recording quality, using Cool Edit Pro, from original live concert recordings, and artist interviews, recorded originally upon a mini disc.

I operate an internet radio station. Travelling light I record live acoustic concert events, and interviews with performers using a mini disc system.

I bring the original recordings back into home studio and record them into Cool Edit Pro via an 8 channel Eurorack MX 802A Behringer mixer, into the on board sound card which is N Force NVIDIA R.

As is normal the volume levels of the various recording do vary a great deal, due to various factors (even the simple fact that whilst interviewing, the person being interviewed will often turn away from the mike and thus the levels drop off)

I use Cool edit Pro extensively when back in studio to ‘refine’ original recordings, and in Multi Track mode to cut and past my program edits together. I was advised that the best method to ‘refine’ original interview recordings was as follows:-

Using the master recording normalise the track to 98%, then effects, amplitude, dynamic processing, settings :
cmp 50 : 1 above -20 dB
exp 2 : 1 below -20 dB
flat 1 : 1 below -30 dB
Compensation Gain = 10dB
Then normalise again to 98%.

The end result is somewhat disappointing, with the final sound quality ‘blurring’ and becoming somewhat ‘like water running through a tap’?

To date the best results with Cool Edit Pro have been by the following method:-

Normalise the original recording to 95% to leaving yourself some ceiling space for adjustments. Then Effects, Amplitude, Hard Limiting, settings:-
Max amp = -1db
Boost input by 6db
Look Ahead Time 7ms
Release time 100

Generally the end results using this method are reasonably good, but I do feel that they could still be significantly improved upon.

My question is simply this, when you are retransmiting performances by quality performers, there is a need to maintain as good a quality sound recording as can be achieved using software techniques available to us from within packages like Cool Edit Pro. In short we Broadcasters can make or break the reputation of a performer or Band, by putting out ‘crap quality audio web casts’. I do not consider that I am an expert in the usage of Cool Edit pro, although I suppose I get to work with this amazing software package far more than most.

If you have any suggestions regarding the above scenario I would be both grateful and pleased to hear from you within the forum or by direct email.

one thing i'm wondering is, is a minidisk recorder considered digital? I would think so, but if it is, maybe you could try running a digital out of the minidisk via SPDIF into your computer. this way the signal would remain digital and you would not lose audio quality due to the D/A conversion.
 
No massive comments from me except to say that I'm a 'hard limiting' fan - and others hate it!.

Also, consider recording the concert material to a Tascam CD-RW4U CD recorder rather than MD - then when you get back to base, it only takes a couple of minutes to 'rip' the recording into your PC with perfect digital fidelity. The interviews for practical reasons would probably be best done on MD.
 
Thanks for the responses Dar & Peter The Ausie.

Regarding digital output from the M.D., this particular model does not have that facility, and accordingly the output is via the analogue, headphone link as an analogue stereo output.

Agree with you all the way Peter with regard to 'Hard limiting V Dynamic processing": for me hard limiting works well every time. Peter's suggestion regarding the Tascam CD-RW4U CD recorder is interesting. In fact this model is no longer produced, but no doubt the company has a successor in it's range. I often wonder why equipment, such as this, is so darned expensive in this day and age, when a high spec computor can be purchased in the UK. for about £700 sterling.

I'll just have to call in some favours from my eldest son: he Production Manages the Football Premiership for SKY. There must be some slightly outdated recording equipment going cheap somewhere.

Anyhow you guys, many thanks for your input. Any more comments will be more than appreciated.

The Tascam can I think still be found here in Melbourne for about $550 Australian - pretty good value really. I have my own and the radio station that I'm associated with has a couple. They've been very reliable on the road, moved in non-specialist cases. I'm surprised they are no longer being made - the only other compact CD recorder is the Marantz portable which is a good all-round solution to location recording, though oddly designed in some ways (eg display on the top so you can only use it standing up!).
