wanna hear the Beatles in audiophile quality.. MISERY! 30 ips ... are there any other 30 ips recordings?? You're Mother Should Know alternate take on Anthology? What about This Boy.. how'd they get that bass so unfettered?
Some specs of the Studer J-37:
@ 15 ips.....30 - 15 000 hz +-2db
But it has NO 30 ips speed. Their quarter inch half track/ full track machines did.
No way any recording at 30 ips would get you better bass. 30 ips will get lower wow and flutter and higher signal to noise ratio. But only on a modern post 1969 machine. 20 - 40 hz is the first octave of bass. 40 - 80 hz is the next octave of bass up. Recording at 30 ips with the Studer J-37 (if you could. Say they altered the machine) will lose you 1.25 octaves of bass.
The Scully 284-8 & 284 -12
@ 15 ips.......35 - 15 000 hz +-2db
@ 30 ips.......50 - 15 000 hz +-2db
I suspect you mean a 30 ips mix down. Same rule applies. You run any half inch half track (full track) tape machine at 30 ips you will castrate the bass. Again at 50 hz. You would get a quieter recording but recording at 30 ips will never get you better bass. That is the mix and recording techniques you are hearing.
However, certain speeds will give bass bumps. This happens in multitracks and stereo/mono tape machines. The 30 ips speed might have caused a bass bump of 2 db or so at 80 or 120 hz. For example many bands who record with the JDF 2 inch 8 track head stacks on 24 track machine will run their tape machine at 7.5 ips. Why? With the 2 inch 8 track head stack the 7.5 ips speed will give a severe bass bump at 25 hz! And this is not the kind of effect you could duplicate with an EQ.
Even in the 1970's this was the case.
All the 2 inch 24 tracks from MCI, Scully, Studer to 3M were:
@ 15 ips....... 40 - 20 000 hz +1/ -2db
@ 30 ips....... 50 - 22 000 hz +1 / -2db
Even the famous Studer A800-24 Mark 1 (1973)
Could not fight it:
@ 15 ips....... 30 - 20 000 hz +-2db
@ 30 ips........50 - 22 000 hz +-2db
As you see doubling the speed really did in the low bass. This is why 99% of audio engineers doing popular music did not run their multitracks or stereo recorders at 30 ips. It would crap the bass. Some did. A few engineers hated Dolby 'A' and used the 30 ips speed option to get an extra 2 db of signal to noise ratio. The 30 ips speed option was often used for copying.
This way you didn't gain any noise and kept your top end spiffy. But it never did a anything for bass.
Of course if you went to +1.5 / 3 db the spec wood look like this:
@ 15 ips...... 20 - 21 000 hz
@ 30 ips...... 40 - 23 000 hz
By the mid 1980's most 24 track machines were:
@ 15 ips...... 30 - 21 000 hz +-2db
@ 30 ips.......40 - 23 000 hz +-2db
Or at + 1 / - 3 db
@ 15 ips...... 20 - 22 000 hz
@ 30 ips...... 30 - 24 000 hz
These are all guaranteed specs by the manufacturers I quote. A skilled audio engineer might get more out the these tape machines. But it depends on many factors. This is why I always list the guaranteed specs. So what specs I list you can be sure the tape machine will perform at those frequencies.
