1. Getting started with AUDIOMULCH

2. Background AudioMulch is not really designed for work in primary schools, and so there is a lot that you may wish to ignore. However – it has two really useful functions: 1. It can play back sounds as they are made, but with effects decided before hand. For instance, if you wanted a sound to be played back immediately with lots of echo, a ‘patch’ can be designed to do just this. This supports improvisation and sound exploration. 2. A soundscape produced live by the children, can be saved to provide a file which can be mixed in other multi-media programmes.

3. Download Information The program can be downloaded from: http://www.audiomulch.com/ There is a 60-day trial version, but this can currently be re-downloaded on a regular basis for free.

4. Volume Controls Before using the programme it is important to adjust your microphone input. This is because you may experience a lot of feedback which can quickly become painfully (and destructively) loud. Before using the programme it is important to adjust your microphone input.

9. Create a patch or ‘mulch’ Open the programme ‘AudioMulch’. Open the programme ‘AudioMulch’. Patches are sound units linked together, which when activated process sound inputs. You can create your own patches in AudioMulch which are easier to use than those that come as standard with the programme.

10. The home screen will already have a ‘SoundOut’ unit. Add a ‘SoundIn’ unit by left clicking and dragging into the central window. Now do the same for two effects: ‘DLGranulator’ and ‘SDelay’.

11. Music patches or ‘mulches’ can also be downloaded free at: http://www.musicwing.co.uk/mulches/index.html which also has help advice on programming your own mulches.

12. Now left click and drag virtual ‘wires’ from each unit. Before proceeding further, mute the sound icon on the top of the screen.

13. Enable Audio Before it is possible to hear sounds you will need to click on the ‘enable audio’ icon, that was muted earlier.

14. Experimenting with sound input Once set up, explore making fairly quiet sounds at first into the microphone to see what comes out of the speakers. Children should decide which sounds are interesting, and explore these further. Input sounds can be vocal, class percussion or other instruments. Some children may want to work alone with the program. In some cases a soundscape may suggest itself. Alternatively you may find you are able to perform a duet with the computer.

15. Changing parameters of sound By double clicking on the effects units, the controls appear in the right hand window. Experiment with adjusting the controls to shape the sound output.

16. Recording Making a recording in AudioMulch is a slightly confusing process the first time you try. The process is not an obvious one, (see illustration next slide). 1. Double left click on the ‘Sound Out’ unit 2. Within this unit, open a file using the open file icon, name it and save in a location of your choice. 3. Click on Save. This highlights the record and stop buttons in the SoundOut unit. 4. Press the red button to start recording and the black stop/play button to stop recording. 5. Once the recording has been made the stop button becomes a play button and you can review the recording and then use in other audio/multimedia programs.
