So, the first thing I do when editing the audio is download everyone’s audio file from the mintCast drive folder and store it in my ‘show file’ for that episode. I then start up Audacity and import all the tracks I will be using to create the edit. At this stage, this does not include the intro and outgoing music or the transition music, as these will be added after the edit is merged down to one track. | So, the first thing I do when editing the audio is download everyone’s audio file from the mintCast drive folder and store it in my ‘show file’ for that episode.

- | As you now have a fairly large audio file, it will take several minutes for this first save, but subsequent saves – as you proceed with the edit – will be virtually instant. One thing to note about audacity is that it is a linear editor, and does not create individual layers that can be removed as you proceed with the edit; so, if you go through several processes and wish to undo one 4 stages back, it means undoing all that work to go back to that stage. So it does mean being sure you are happy with each editing process before moving forward – or you could have to undo a lot of work to fix an issue you did say 30 minutes ago. | + | As you now have a fairly large audio file, it will take several minutes for this first save, but subsequent saves – as you proceed with the edit – will be virtually instant.

- | You can do this to each individual track separately, or highlight all the tracks and do it as one process, but this will take quite a while depending on the number of tracks being compressed and the power of your PC. In this case, on a Dell E6540 with a 2014 core i5 mobile CPU with 16Gig of RAM, it took over 35 minutes. | + | You can do this to each individual track separately, or highlight all the tracks and do it as one process, but this will take quite a while depending on the number of tracks being compressed and the power of your PC.

- | The next step is to use the silence at the beginning of each track to reduce the ambient noise recorded locally by each of the members. First, we highlight the area of the track where we recorded the silence on the track we wish to reduce the noise on. In this case we will have to do each track separately as the background noise in each location will have been different. So, after selecting the silence on the track, we again navigate to the Effects menu but this time pick Noise Reduction and this box (above) comes up. | + | Ainsi, une fois le projet audio sauvegardé, l' |
- | This first time you are going to choose the Get Noise Profile button click this then when this is completed only a second or so. After selecting the whole track this time, re-navigate back to the noise reduction dialogue box and set your noise reduction parameters; the settings you see are what we use now, but we have got here by trial-and-error to get what works for us. When you have set your levels, then press the OK button that this time will be activated as you have now got a profile for the noise reduction tool to work with.

If all the tracks move together, go to tracks on the menu bar, and, at the bottom, make sure the sync-lock tracks is off by unticking the box; we will be resetting this after lining the tracks up.

+ | **In most cases, a second pass is all that is needed to reduce the ‘silent’ recording area of the track to zero, but, in extreme cases, it may require a third pass; if so, it is important to see if this has affected the sound quality of the voice areas as it may be a compromise to leave as it is without a third pass of noise reduction, but generally two passes is all that will be required. | ||

+ | So, finally this month, we will look at the process of ensuring all the tracks are in sync, as recording over the internet can lead to a little bit of lag in sound. In last month’s article I said how we begin the recording with the 3,2,1, record, and the 25 seconds of silence, which is then followed by a 3,2,1, Zero, where on the Zero we all say ‘Zero’ this gives us a marker to line the tracks up as closely as possible. First we need to select the track moving tool which is the double-pointed arrow in the box next to the Red record button.** | ||
