Thanks peoples - Don't understand a couple of points:-(

Fullerton - I have used a software compressor (I think) - WavePad. Does Audacity have the ability to output a wav file that will play at 15dB. Bringing me onto my next question...

Foolestroupe - Don't understand that at all. 15dB isn't relative to anything is it? Isn't 15dB a measure of 'loudness' - like 15cc is a measure of volume or 15 grams a measure of weight? I assume that when they say that the the wav file output needs to be set to 15dB they mean when it plays on a pre-determined device - In this case our telephone switch. Am I missing something? If so can you explain to me - Preferably in words of one sylable so I can understand it:-)

Bernard - may well take you up on your offer - I want to bring my concertina round for a dose of looking at anyway:-) Trouble is I will need to convert a few tracks so the rest of the crew can decide which one they want to use - And I will need to include some pop dross - Are you sure your equipment will not reject it;-)

Cheers
