Delay is the quick repetition of a sound and can be played at different speeds. This will sound like an echo

REVERB
REVERB
Reverb is like delay but more subtle and the individual repetitions of the sound are not heard. Adding lots of reverb will make the track sound like it is being played in a large room such as a cathedral.

To apply DELAY or REVERB in a live setting you need an effects pedal, an effects setting on an amplifier or a multi-effects processor which nowadays is often built in to the mixing desk. To add reverb to a recording, you can add a plugin.

A movement within the sound, but a bit flat and ‘phasey’. (A bit like 2 violins playing together with one spot on with pitch and the other doing the lottery. It has a distinctive sound once you have listened to it a few times.

FLANGER
The flanger is a tricky one to describe without getting into a lot of technical detail. Basically, it is a very intense effect which can sound a bit like chorus, depending on how it is set up. It shares similar electronic principles.

This is a problem which rears its ugly head when you couple microphones being too close to speakers in a PA system and excessive gain. Electric guitars being played too close to their amplifiers can exhibit the same phenomena, although this can be used to artistic advantage - e.g. have a listen to some Santana tracks.

Hiss can occur for 2 reasons:
1. In the days when tape was widely used, hiss was a regular problem. Ways of minimising this, included using ‘Dolby’ - keeping signal levels as high as possible and, of course, buying the best grade of tape. The example you hear is of ¼” tape of poor quality.

2. The other source of hiss, which is still with us today, exists whilst using low quality/budget high gain circuits - such as microphone pre-amps. Basically, you get what you pay for!

3. Earthing problems can also cause hum, but the remedy has to be treated with caution. If you have a problem with hum, which you suspect may be due to this reason, do not attempt to solve it yourself - contact an expert.
