Lab 08

Making an "old" sound

For this lab, you have to modify a sound file with two effects to make it sound "old", like in old recordings. The first effect is to add some noise to the sound, which is one characteristic of old recording and playback technologies. The second effect is to modulate the volume of the sound to vary in a rythmic pattern. This is to simulate how old record players played a vinyl record. Here are a couple of sample sounds files. You have to right-click and select "Save Link As..." to download them. An example how the result should sound can be found here (for the second sound from the list above).

Lab Questions and What to Turn in

As mentioned previously, you have to add comments with your own identification (name, student ID, date). Remember to save the file after you modify it!

How to submit the lab

Exactly like in lab02, you hand in this lab the submit command on the Linux syst ems that are behind the PRISM lab infrastructure. For details on how to submit, please refer to lab02. However, this time please submit to lab08, i.e. issue the command
