Week 4

This week we discussed Audio recordings and podcasts. This file types can be stored as MP3’s, this is a patented digital audio encoding format. It is a common audio format for consumer audio storage. Also the Waveform Audio File Format or WAVE/WAV, is a Microsoft and IBM audio file format for storing audio data. It is the main format used on Windows systems for raw and typically uncompressed audio. There are also AIFF and OGG formats.

When recording the background noise of your recording is known as Ambient Noise. This can add to the sense of authenticity in a recording, but too much background noise can interfere with the quality of a recording. Also sounds bounce off flat surfaces. So the softer and the more textured the surface, the less the sound bounces off it.

The types of devices you can use to record are:

Dictaphones:

Low in price, but poor quality.

Mini Disc recorder/player:

Relatively low price, good quality recording for analogue.

Smart Phone:

Price depends on phone, digital audio.

MP3 recorder/ player:

Medium-Higher price, high quality digital encoding.

Alternatively, you can use a headset connected to a PC:

Low price, high quality digital encoding depending on the PCs built in sound card.

We were also told about ‘Audacity’ the free, cross-platform sound editor. It is free, open source software that allows to record and edit sounds. We were shown how to install and use Audacity. I look forward to using Audacity and trying to make my own recording.

For this weeks photography task we have to demonstrate the effect of shutter speed on a moving object.
