Frequently asked questions

Which types of records and reel to reel's do you restore?
We can restore 33 1/3, 45, and 78 rpm records in 7", 10", and 12" sizes. We can also restore most 1/4" reel formats, including 3.75 i.p.s., 7.5 i.p.s., and 15 i.p.s. reels as well as any standard sized cassettes.

How much damage can a record or tape have and still be restored?
We can't give an answer without hearing the source. Bring it by the studio and we can assess the damage.

What format do you restore the recordings to?
A CD is the standard format, but we can also provide restorations as 24bit digital files, or various other digital formats including MP3.

How much does a restoration cost?
Projects are charged by the amount of audio restored. The cost varies by the amount of processing done to eliminate extraneous noise (e.g. a straight transfer of the source to a digital format would be the most inexpensive process.)

What happens during restoration

First, the source is prepared for the best possible transfer. With records this includes a thorough machine cleaning, with alcohol-free solution for shellac-based 78s, eliminating the dust and static charge on the record. For reels the tape may be "baked" if it is deteriorating. Baking allows the tape to temporarily hold together for a transfer, and can improve the fidelity of a reel.

Then using high quality components the recording is transfered to a computer. With special software, we edit and remove noise from the track, depending on the level of processing you request.

Finally, we record your restored tracks onto the media you specify, typically a CD.
