|---|---|---|---|---|---|
| show | character
🗑
|
||||
| show | most basic sound, simplest type of wave you can have. have flute-like character. No harmonics. (flute has a sound that contains very few additional frequencies)
🗑
|
||||
| sounds are made up of multiple... | show 🗑
|
||||
| complex sounds have... | show 🗑
|
||||
| harmonics | show 🗑
|
||||
| show | the first harmonic
🗑
|
||||
| second harmonic | show 🗑
|
||||
| show | 3X the fundamental
🗑
|
||||
| show | if all harmonics are present at the same relative amplitude. sounds like garbage.
🗑
|
||||
| square wave | show 🗑
|
||||
| Why can't you make a square wave with all even harmonics? | show 🗑
|
||||
| show | ex. square waves and sawtooth waves. basis of analog subtractive synthesis (Moog, ARP, Buchla, etc.) (subtractive synthesis is filtering parts of the sound you don't want to hear)
🗑
|
||||
| harmonics vs. overtones | show 🗑
|
||||
| How do we differentiate 'voices'? | show 🗑
|
||||
| What determines the harmonics content of your voice? | show 🗑
|
||||
| show | graph that indicates from left (low) to right (high) the frequencies that you're hearing
🗑
|
||||
| Different vowel sounds have... | show 🗑
|
||||
| Sibilant sounds have... | show 🗑
|
||||
| What happens if you filter out too much high frequency? | show 🗑
|
||||
| show | musical term for harmonic character of different instruments
🗑
|
||||
| What are the two categories of sound? | show 🗑
|
||||
| pitched sounds | show 🗑
|
||||
| show | indistinct fundamental frequencies and overtones. drums and cymbals and any other non pitched rhythm instruments. Have frequencies that aren't multiples of the fundamental, so they're called overtones, not harmonics
🗑
|
||||
| What determines our perception and recognition of a sound? | show 🗑
|
||||
| envelope | show 🗑
|
||||
| show | frequency, amplitude, and timbre (all change over time)
🗑
|
||||
| show | ...representation of the envelope
🗑
|
||||
| show | attack, decay, sustain, release
🗑
|
||||
| show | energy enters the piano string, amplitude grows
🗑
|
||||
| decay | show 🗑
|
||||
| show | amplitude changes very minimally
🗑
|
||||
| show | sound ends. wave gets a little louder because you lifted the pedal up (for a piano note)
🗑
|
||||
| show | difference between quietest and loudest sound accurately produced by a system. speech, music, movies, sound systems, etc. all have it.
🗑
|
||||
| If multiple systems are present (i.e. cassette tape, amplifier, loudspeaker)... | show 🗑
|
||||
| show | level at which a system cannot produce sound without noise overcoming the signal. all signals carry some noise. e- in devices generate some level of noise that represents flow of e- through the circuits. represents lowest amplitude a device can produce
🗑
|
||||
| show | ...the lower the noise floor
🗑
|
||||
| show | happens when a device is outputting its highest possible level of amplitude. nice and curvy sine wave has flattened peaks. becomes, essentially, square wave. makes sound seem harsh. over time can damage loud speakers
🗑
|
||||
| clipped flattened tops represent... | show 🗑
|
||||
| show | ...to keep signal above the noise floor and below clipping from source to output
🗑
