Hello this is a some radio chatter that i was working on it goes in and out the a cut at the end.

Using a variety of 1980s radios connected via a headphone output to the computer, i tuned in - across the entire bandwidth - of the mw and lw channels. I also captured the static hiss of those bands, 'dead air'. There are small clips of various stations along the way but i was looking for that 'tuning in' sound that was so familiar when radio was the central part of every teenager's life.

Cell phone vibrating on a hard surface, recorded from within. I put a htc wildfire smartphone on top of a turned-over plastic ikea bin and a zoom h2 under it. This sound is cc0 but i highly recommend that you include a link to this page when using it, to avoid misunderstandings. Http://farm9. Staticflickr. Com/8070/8213683889_517a10ef52_o.

This is from my royal typewriter that i picked up at the thrift store for 5 bucks. It works great and i use it quite a bit to write letters with. I love the feel and sound of the keys. I used two yamaha pocketrak recorders to record it. If you use it please comment on what you will use it for. Thanks. :^).

Residual output sound obtained by analysis and synthesis of veena concert sound (https://www. Freesound. Org/people/anjds/sounds/377315/ ) with harmonic plus residual model implemented in the sms-tools software package (http://github. Com/mtg/sms-tools)parameters used in analysis are :- window type = blackman, window size(m) = 1575, fft size(n) = 2048, magnitude threshold in db(t) = -100, minimum duration of harmonic tracks = 0. 01, maximum number of harmonics = 100, minimum fundamental frequency = 100, maximum fundamental frequency = 800, maximum error in f0 detection algorithm = 5, max frequency deviation in harmonic tracks = 0. 01.

This sound came from a finite difference 1-dimensional wave simulation with the friedlander waveform as the force acting in its middle.

This is a transformation of the original recording https://freesound. Org/people/pinehadmz/sounds/369501/. For week 10 "musical piece" assignment for the audio signal processing for music applications online class. There are three layers, panned in stereo. Each syllable of each layer was randomly pitch shifted to a note in the minor scale using the harmonic plus stochastic model. Each harmonic track was thickened with extra harmonics during the synthesis process too to make it extra weird.
