“Old Engines Grab Bag” is a pack of numerous old, unique and characterful engines from early 1900s. It’s a massive collection of 56GB multitrack 192kHz recordings of old tractors and stationary engines, both diesel and gasoline fueled.

The intention wasn’t to cover vehicles driving, but to get isolated and very closely recorded mechanical elements of engines and exhaust pipes as a source material for sound design. There are many starts, idles, revs, offs, RPMs variations, backfires etc. Some are heavy and large sounding, some are small and funny. Tractors were captured EXT and most of stationary engines INT, but since they are very closely recorded there is just a little amount of reverb on most of them.

Most of engines are 1 or 2 cylinders and low horse power and their RPMs are also low. Thanks to this, many of those sounds aren’t tonal and can easily be used as additional layer with other design elements. They work great for adding vintage character, designing junky or funny vehicles, crazy huge steampunk machines or engines malfunction.

Sounds were recorded using multi-mic setup: Sanken CO-100k (most of the time pointing mechanical parts), Sennheiser MKH-8060 (mainly for isolated exhaust pipe), Schoeps CMC6XT mk41/mk8 (general image) and part also with Trance Audio Inducer contact mics (adding unique mechanical perspective).

The library is delivered as multitrack 192kHz files, as well as stereo mix of all microphones. Thanks to using microphones with extended frequency range, drastic pitch changes can be applied.
All files have extensive metadata created in Soundminer, including leg picker with microphone labels.

Demo files include pitched sounds, which are not delivered with library.
