Stento

Preservation Lab

Send us the tape before it stops playing

A working audio transfer lab inside a charity, open to anyone in Canada. Flat published rates, no minimum order, a condition report with every job, and the surplus goes straight back into free kit loans and public access. We have transferred 4,180 hours and lost none of them.

The signal chain

One pass, real time, nothing “improved”

Preservation transfer means capturing what is actually on the carrier, including the hum and the dropouts. We do not de-noise, de-click or normalise the master. If you want a cleaned listening version for broadcast, we make that separately and keep both.

Rates in Canadian dollars

What each carrier costs

Getting a quote takes one email

Tell us roughly how many carriers, what types, and whether anything smells musty or looks furry. Photographs help enormously. We reply within two working days with a written estimate and a bench date.

  • No minimum order — one cassette is a real job
  • Estimates are fixed, not indicative
  • Nothing proceeds without your written go-ahead
  • You keep every right you had before you sent it

If you smell mould, stop

Do not open the box indoors, do not play the tape, and do not try to clean it. Seal it in a bag, keep it cool and dry, and call us on (902) 555-0187. Mould spreads through a collection in weeks and a single play can shed the layer that carries the recording. We quarantine and treat mould-affected carriers at no extra charge for charities.

Bigger projects

Commissioned collections, start to finish

Municipalities, unions, museums, universities and community associations bring us projects where the interviews have not been recorded yet. We design the sample, train and supervise the interviewers, run the recording, then transfer, describe and deposit the result — with your organization named as the collection's originator.

Typical size

30–80 interviews

Six to eighteen months from scoping to a catalogued, opened collection.

Typical budget

$14,000–$90,000

Quoted in stages so a project can pause between funding rounds without loss.

What you keep

Everything

Copyright, credit and a full set of files. We hold the preservation copy and provide public access on the terms your narrators chose.
