Recording Audio - bit rate and sampling

Overview When recording audio, vinyl, audio cassettes, or reel-to-reel, we should be recording in the highest possible rate;  24bit and 96KHz.

Spoke to John Sawa ( www.johnsawa.com ), an audio editor.  Asked what the different is between 16bit and 24bit and 44KHz and 96KHz.  As he explained, if you have the higher rates, you have more room to work with if you are trying for fix the audio.  If the audio is really good, it will not make much difference.


Ran a test of a BC Library audio book and found the different options made very little difference.  Ran combos of 16bit and 48KHz and 24bit and 96KHz.  Also, with the 24bit option I tested Dolby C on and off.  The conclusion was that the 16bit and 24bit combos made no difference.  The tape quality was good so that may have impacted the results.  Dolby C off made the low noise bits in the recording a little more defined and the vocal bits made no difference.  Here's a Vegas screen of the wave files (1st line 16bit,48KHz with Dolby C, 2nd pair 24bit, 96KHz, with Dolby C, and 3rd pair 24bit, 96KHz, no Dolby):

When you set up Vegas, make sure the properties of the project have the audio set to 24bits and 96KHz.

Vinyl Records - Digitizing

Overview This article provides information on digitizing vinyl records.


Audio Technica AT-LP120 USB turntable, 78 stylus (yellow), jeweler's flat balded screw-driver, MUSIC (recording PC), stereo system, Magix Audio Cleaning Lab software.

Change Stylus (needle)

We have two stylus, one for LP's and 45's (green), and one for 78's (yellow).  Never play a record with the wrong needle (it can play but it WILL damage either the record or stylus or both).

1)  Release the headshell assembly from the tonearm by turning the locking ring clockwise.

2) Carefully remove the headshell assembly and turn it over so the stylus is pointing upward.

3) Remove the stylus by taking a flat bladed jeweler screwdriver and carefully prying the stylus assembly from the cartridge.  Pry between the belly of the cartridge and the plastic assembly holding the stylus.  The stylus assembly should come straight up from the cartridge.

4) Push the replacement stylus assembly straight down onto the belly of  the cartridge until it fits snug.

5) Replace the headshell assembly back onto the tonearm and lock with the locking ring (counter clockwise a few turns).

6) The counterweight should be adjusted for the different stylus:

a)  33/45 stylus:  about  1.8 grams

b) 78 stylus: about 2.1 grams
