This helicopter sound design was created at fl studio, in the sytrus synthesizer. The sound consists of four layers. 1. Sine wave frequency of 44 hz. Simulates the low frequency noise of propeller blades. 2. White noise passed through the svf filter. Simulates the noise of propeller blades. 3. Saw wave. Simulates the sound of an engine. 4. The sine wave. Imitates a high-frequency whistle of the engine. Various modulations are applied to all waves through the envelopes of the synthesizer. Next, the signal on the mixer channel is processed by a multi-band exciter and equalizer. Then a signal was sent to two channels with delay processing. One of them imitates reflections. In the lower-middle frequency range. On the second in the upper-middle frequency range. As you approach the sound source, the volume parameters of the direct and reflected signals are automated, low pass filter, pan width and equalization of direct sound. The helicopter performs strange maneuvers, as if making constant circles during the approach to the listener. I did not seek to create the veracity of these maneuvers.

A recording of several single notes on the ukelele. Noisy, not a totally clean recording either (some bleed from a c string that i didn't intend to touch).

This is a fragment from the aria ah mes amis at a lower pitch and badly performed. Iintend to use it for a coursera homework (audio signal processing for music applications). The intention is to transpose it and simulate a morfing like a falseto to the true key where the tenor hits high c, which i obviously cannot hit, otherwise i wouldn't be taking coursera courses and uploading to freesound. . .

Studio technologies - stereo simulator (generation ii). Https://studio-tech. Com/products/generation-ii-stereo-simulator/. The generation ii stereo simulator from studio technologies creates a convincing stereo imagefrom a mono audio source. The fully mono-compatible signal simulates space withoutreverberation by using random, non-recursive filter techniques. The mode switch (found on the hardware unit) controls the overall sound of the generation ii. In the music position, the full audio bandwidth of the input signal is simulated. This mode isappropriate for audio material with little or no voice-only content. In the music & voice position, the input signal is sent through a band-reject filter prior togetting sent to the simulator circuits. This creates stereo simulation over the low and highfrequency range, while limiting simulation in the voice band. This mode is appropriate for audiomaterial that contains voice-only content, such as a film track or television show. The stereo intensity control determines the amount of stereo simulation that is produced. Inthe fully counterclockwise position (ir files “0” – included for process comparison), no simulatedstereo is produced. The mono input signal is sent equally to the left and right outputs. As thecontrol is turned clockwise (ir files “1 – 6”), the amount of stereo simulation increases.

A recreation of a lavalier microphone pop. Useful for reality or documentary where an interviewee may rip off their mic or you simply want to create the illusion of that drama. Also useful to incorporate into a "signal lost" effect, etc. Processed with some limiting so it's tamed and ready to throw in a mix. Recorded with an mxl lsm-3 dynamic mic, no reason to abuse my real lav mics.

This sound is a 1-sample long impulse at 48 khz. It covers the whole frequency range with equal power. This is a perfect sample for exciting your guitar amp or reverb unit to capture it's impulse response (ir). You can also play it through a speaker in a reverbant room to capture it's reverb characteristics. Remember that the ir sample will be no flatter than your speaker's performance multiplied by your microphone's performance (frequency response characteristics). The sample has exaclty 1 second of silence, then the impulse, then another second of silence to ensure the impulse will be played clean and untruncated on any sound system or device. My test with ir lv2 convolution plugin have proven, that this sample has absolutely flat frequency response - convolved signal was identical to the source signal. After normalization and sample-alignment of the sound clips i have inverted the polarisatin of one of them and summed them - result was absolute silence, even no hiss was present as a result. This shows the accuracy of the convolution process and proves this sound to be perfect for sampling ir. The impusle was generated with c* dirac ladspa plugin. Created using audacity.
