WorksheetsSonic-Pi: Duration with Envelopes
Total questions: 14
Worksheet time: 7mins
Which statement about amplitude is true?
All audible sounds start and end silent and contain some non-silent part in-between
All audible sounds end silent and contain some non-silent part in-between
True or False?
An amplitude of 0 is silence and an amplitude of 1 is normal volume.
True
False
The only part of the envelope that’s used by default is the ____________ _______
(a)
The ____________ _________ is the time it takes for the synth’s sound to fade out.
(a)
True or False?
All synths have a release time of 1 which means that by default they have a duration of 1 beat
True
False
The duration of 1 beat has a default BPM of (a) and lasts 1 second)
You can change the (a) of your sound by changing the release time.
By default, the attack phase is (a) for all synths
True or False?
Sonic Pi’s ADSR envelopes have the following phases:
1. attack - time from 0 amplitude to the attack_level,
2. decay - time to move amplitude from attack_level to decay_level,
3. sustain - time to move the amplitude from decay_level to sustain_level,
4. release - time to move amplitude from sustain_level to 0
True
False
The attack phase is the time from __ __________to the attack_level
(a)
The decay phase - time to move amplitude from (a)
-level to decay_level
The sustain phase - time to move the amplitude from (a) _level to sustain_level
The release phase is the time to move (a) from sustain_level to 0
It’s important to note that the duration of a sound is the summation of the times of each of these phases. How many beats will the following sound have?
play 60, attack: 0.5, attack_level: 1, decay: 1, sustain_level: 0.4, sustain: 2, release: 0.5
5.4 beats
3.4 beats
4 beats
3 beats
