Hi Martin, here are some more detailed instructions for using Audacity to create the example you wanted.
1. Open audacity. 2. On the track menu, open the add new sub menu, and choose Audio track (ctrl+shift+n). 3. Open the Tone generator dialog from the Generate menu. In this dialog, the duration control is like a spin box. By default, the format is seconds which are grouped into two groups of three digits, and the default time is thirty seconds. To change this to one second, press End to move to the last digit, press left arrow to move to the digit 3, and then type in the digits 0 and 1. Note Jaws then reads out zero zero zero, but that's because the focus has wrapped around to the first group of three digits. 4. The generated tone is selected, so to deselect this and move the cursor to the end of this selection, press right arrow. 5. Open the silence generator dialog from the Generator dialog. Although the default duration is read out as zero, this is a bug, and in fact it's 30 again. So to change it to one, press end to move to the last digit, and follow the insructions in step 3. 6. The silence is selected. Select all the audio by pressing ctrl + A, and then choose duplicate from the edit menu. so that you now have two identical tracks. You can move the focus between the tracks by pressing up arrow and down arrow. 7. Both tracks are selected, and a time range covering all the audio is selected. To deslect track 1, move to the first track and press enter, which toggles the selection of a track. So with track two selected, choose the Reverse effect from the Effects menu. Track two now contains silence followed by the tone, rather than the other way round in track one. 8. Set the pan control of track one to fully right, and the pan control of track two to fully left. To change the pan of the focussed track, press shift+P which opens a pan dialog. Type in 1 for pan to right, and minus 1 for pan to left. 9. Select all the audio by pressing ctrl+a, and then open the repeat dialog from the effects menu. specify how many repeats of the selected audio you want. 10. Press home to move the cursor to the start, and then spacebar to play/stop. The Jaws guide I mentioned has more details: http://vip.chowo.co.uk/wp-content/uploads/jaws/Audacity-1.3.8-Guide.html David. original message: I am a complete new comer to the world of audio editing. I would like to make an audio file consisting of two channels. That is to say, different information being presented to each ear piece simultaneously. Would this be possible using a programme such as Sound Forge. I have a demo copy of version 9, but it all seems rather daunting to me. Any suggestions would be very helpful.
