Default Hiss and echo removal

I've received an unexpected request to try and remove some excessive hiss and echo from a WAV file of an interview which took place in a gym using a poor microphone. As I've been asked to try and get this done for a project asap, I was wondering if anyone had any suggestions for how to address this using PT10. Can it be done effectively with PT10, or do I need to purchase something like Wavelab?

If you want to do it quickly, you might try the demo of a couple of programs. Izotope RX is a good one, as mentioned. Also try Waves Z-Noise and X-Noise.

This will address the hiss, but for the echo, that's harder to do. Your best bet is to try the Expander/Gate plugin that comes standard in Protools (Dynamics III, I think). You can try to set it to cut off the echo in between dialogue.

Thanks for the suggestion Craig. It looks like an excellent product. However, as my focus is on songwriting and recording it is unlikely that I would have the need to use Izotope RX again. I believe it costs about $350, so I don't know if I could justify the expense for this one short project. I was considering buying Wavelab at some point, primarily for CD burning, but I understand it also has audio repair tools.

Hi

Magix Audio Cleaning Lab did a great job for me on a project I thought was hopeless. A 50 year old recording pressed to 33 1/3 in a church with one microphone 50 feet away from the wedding couple. Echo, car horns etc.
There's a spectral type remover tool in there where you can cut out the offending band of noise or specific events. You can even sample some of the noise , hiss etc. and filter based on the sample.

For $60, it's worth a try. Magix even has a demo I believe.

good luck

There must be a demo that you can try. Unless it is crippled in some way it should be able to do the one job without you having to pay for it.

Sound Forge comes with excellent noise removal tools.

Thank you to everyone who took the time to reply and provide some very useful information. Given the time constraints I ended up using the Pro Tools Channel Strip as well as the Kill EQ plug-in to improve the quality of the audio clips. This may be adequate for his preliminary submission of his video later today after he finishes some editing. If some of the more aggregious sections can't be masked with his background music soundtrack I'll buy or demo one of the suggested software tools.
