How to use a modern turntable to convert phonograph records to digital format for cd's

The speed conversion is indeed a good workaround if you’re table doesn’t have 78rpm. There are couple of things you’ll want to do if you’re serious about 78rpm transfers and this turns out to be an ongoing thing. One, it sounds like you’re using a stereo LP stylus. For a couple of “one off’s”, this does work. But if you want better sound, you should look into getting a wide groove stylus designed for 78s. The reason is that a typical 78 from this era has a much wider groove than a stereo LP. So when you play it with a stylus designed for modern records, you’ll pick up a lot more noise since the stylus is riding along the bottom of the groove. Years ago I made a video demonstrating this: kzfaq.info/get/bejne/nLKGrMiBvL7RiZ8.html Another thing you’ll want to look at is equalization. Records made from about 1956 on, were made using the RIAA emphasis equalization curve. When played back through a modern phono preamp, the opposite de-emphasis curve is applied. Unfortunately, these 78s were made before the RIAA standard existed, so playing them through a modern preamp won’t sound accurate unless you compensate for the difference. Also, the EQ will vary depending on the label and year the record was pressed. The good news is that these have all been documented over the years, and you can easily find suggested EQ curves online. To make things a bit easier, there is a plug-in you can get for Audacity that lets you input the correct turnover and roll off values for the particular 78, and from those values it will create a preset which you can then import into Audacity’s EQ filter. Since you’re doing the 45-78 speed conversion, you’ll want to do it in this order: 1, record to Audacity 2, to go the EQ filter, select the RIAA preset, check the “invert” box, and apply it to the recoding. 3, do your 45-78 speed conversion 4, apply the correct EQ that was used when the record was pressed

The thing about using a 33 1/3 or 45 stylus on 78 rpm records is the 78 rpm grove is cut to move the needle left/right and the modern LP groove is cut to modulate the stylus roughly up/down. The old hand-cranked Victrola 78 rpm mechanical sound reproducer is made to convert the left/right needle movement into a sound wave from a mica disc vibrating left/right. The 78 groove width is HUGE compared to the LP groove, which is why LP groove geometry puts more info on a disc than a 78 groove. It would not be my preference to convert 78s using a modern LP stylus at 33 1/3 or 45 rpm UNLESS you were using a modern stylus designed for 78 rpm groove geometry.

Hell9 Blake, what needle and arm are you using?
@BlakesGarage12 жыл бұрын
This is the factory linear tracking Sony arm, I believe the needle is an audio technica 78rpm cartridge in a p mount. The turntableneedles.com stock number is bc78rpmt4p
