Old epson printer trying to print something on a sheet of paper. The ink was completely dry, that's why the sound may vary a little bit from a "standard" unit. Delicate noise reduction performed.
It's a recording of a modern portable cash register printing a daily report. Then the paper tape is ripped of. There are funny frequency effects caused by the paper tape getting longer and resonating different frequencies. The sound have not beet piped through any processing. Recorded with a hand-held zoom h2's rear mics. Originally 96khz/24-bit wav. Edited and converted to flac using audacity.
I mixed, slowed down, and sped up different small chunks of an audio file of a glitch noise, making something that sounds like a receipt printer at costco/walmart/freshco/any other big store chain.
D min7 chord of a halion 6 patchmultisample (c0-c6). Source: zebra 2, spectro blend oscillators (additive synthesis). Strong processing with spectral fx (esp. Mtransform), eq/geq + compressor to balance the frequency spectrum. Feel free to suggest/demand other chords. Don´t hesitate. . .
