Avicii samples/sounds?

[Ingvardo]

Can someone tell me which three samples/sounds Avicii use in this song?

1. The impact/lazer/oneshot kind of thing at 0:55

2. The uplifter kind of thing (sounds like a helicopter propel) that starts just before the sweep from 1:04 to 1:09

3. Which sound from (probably nexus or sylenth1) does he use from 1:40

1. The impact/lazer/oneshot kind of thing at 0:55

Highly/Self resonant filter sweep over White Noise

2. The uplifter kind of thing (sounds like a helicopter propel) that starts just before the sweep from 1:04 to 1:09

Probably Amplitude modulation (AM) where the amount of modulation and/or pitch offset is controlled by automation or envelope. The "helicoptry bit" is when the pitch of the modulator is offset to a less harmonic ratio so that you get fast quivering effect. Then at its end it modulates towards a harmonic ratio.

Amplitude modulation produces the sum and difference frequencies of all partials in the spectrum of carrier and modulator. E.g. When using sines (just 1 partial) for both carrier and modulator. E.g sine1 440 Hz, sine2 at 110Hz will give a spectrum of 440 +/- 110 = 330 Hz and 550 Hz. It's a often a recognizable effect. Especially on a pitch sweep one of the 2 signals. This results in an upward and downward sweep (summ and differences increase). Start with simple spectrum oscillators like Sine and/or Triangle or it will go chaotic soon.

Some practicalities/examples can be seen and heard here on an analog (mini) modular, but you don't need one:

3. Which sound from (probably nexus or sylenth1) does he use from 1:40

At least 2 layers. The first in white noise through an (opening) filter. Probably bandpass, not to steeply resonant. Quite a wide bandwidth. Maybe a Highpass/Lowpass combo have more control over the bandwidth and slopes. The second is probably something like a saw through a highly resonant highpass filter, rising in pitch.

The good news.

These are things that most "subtractive" synths can do. Though AM is not found on "all" subtractive synth. There are many synthesizers you could use. Hardware or software (commercial or free).

The bad news....

I'm not guessing what exact synths were used. There are many, many variables. Both in the generator (the synthesizer) and the effects (further "downstream" in the chain/proces). Even if you know what synths/effects were used, you probably won't get the exact same results. Even if you exactly know what patch/preset was used you will probably not get the exact same results.
