Telephone Recordings

Our Telephone Recordings

B-series recordings were recorded using a pickup coil. Audacity was used to remove noise and to digitally amplify certain portions.
I-series recordings were recorded using Audacity WASAPI. Only the distant end (called party) was recorded (my voice was not).
P-series recordings were recorded using a pickup coil. No digital amplification was performed, to preserve the original levels.
Left-click to play, right-click to download (click Save Target/Link As). Audio may not play on mobile devices; use a computer.
Mirror links are backups of the primary Download links. The mirror links may not have player controls depending on file type.
We welcome your feedback! Please leave us a message by contacting us.

Warning: B-series and I-series primary download links will not work after 12/30/2018. Only the mirror links will work after that.

Recording Notes:

P2/P4 - This payphone does not allow coin calls. If you listen to the recording, whenever a local or long-distance number is dialed, you can hear the prompts asking for a coin deposit.
However, the phone physically will not take them, as a lock is inserted onto the coin slot and the phone is essentially good only for toll-free calls. This is more common in high crime areas.
P7 - Not sure what this is; the recorder was accidentally left on. But it sounds cool, so I'll leave it up. Parts of it sound like slowed down dial pulsing!
P8 - I did actually deposit 50 cents at one time. The call did not go through; instead, I received the error message of nonexistent number you hear in this tape.
P9/P10 - This was NOT the pickup coil receiving interference; the line actually had TONS of *intelligible* analog crosstalk! Check it out! Super analog sounding.
P11 - This is what you hear when you dial into this COCOT from another phone and you answer it on the first ring. You don't get connected with the caller; you hear this.
P18 - Not recorded, but I separately dialed all the N11 codes, except for 911. None of them worked.
P20 - The technique used to get directory assistance is not special to payphones.
