Title: Can I use ISDN as a phone patch?
Post by Peter on Apr 20^th, 2010 at 1:22am

I'd like to use my ISDN line as a phone patch. If I call my ISDN on another phone line, I can hear myself talking through the mic. However, I cannot hear the playback of anything recorded. How can I get the playback to be heard down the phone line as well as on my own monitors?
I am using a PC with Windows XP, I have a Creative Audigy II sound card, AudioTX Comunicator codec and WavePad 3.05 as a sound editor.
Many thanks.
Peter.

Hello Peter,

AudioTX Communicator will indeed answer standard phone calls on your ISDN line and act like a phone patch. Even with a standard setup (mic and headphones) you will be able to make a normal phone conversation with AudioTX Communicator.

How do you playback the recorded material? Do you use the "file play" system that is built into AudioTX Communicator or do you play it back through WavePad?

If you are using WavePad then you will need a separate sound card to output the audio and a small mixer to mix it with your mic signal and get it into the inputs of the sound card used by AudioTX Communicator.

If you use the "file play" system of AudioTX Communicator then it should just work out of the box.

Best regards,

Edwin.

Thanks Edwin.
Sorry for not respoding sooner. I thought this site was going to email me when there was a reply to my topic but nothing arrived.

I play back through Wavepad. I've tried the file play function in AudioTX but that seems to be only for cueing up pre-recorded files. Once I'm connected, I cannot play files I'm currently recording - which surely is the point. If you know a way around that, I'd really like to know.

Peter.

Hello Peter,

The file playback system in AudioTX Communicator is indeed meant to playback pre-recorded items. Like for example a reporter in the field would do - interview people in the street and later while being live on air playback the interviews as part of the report.

If you want to playback a session that you just recorded with Wavepad then you need a separate sound card for Wavepad. This then allows you to use a little mixer to mix the output of that sound card with the sound of your microphone and offer that audio on the input of the sound card used by Communicator.

The reason for using two sound cards is that you want to keep the audio received from the ISDN separate. If you do not keep it separate then the person on the other side will receive their own audio back as a nasty echo.

Best regards,

Edwin
