Work Flow for reel-to-reel recordings of LPs Please comment.

<<<The high pass filter to remove rumble has three parameters to set.>>>

Rumble filters have one interesting problem. Most people can't hear them work. You certainly can't use "computer speakers" and most entertainment systems won't go down that low, either. The limit of human hearing is generally said to be 20, which means even if your speakers do go down that low, you won't be able to hear the filter work.

Have you ever been to a cathedral and been struck by those musical notes that you didn't so much hear as feel as your chest moved? That's 20 Hz -- or maybe slightly up from there. You can also get those tones from the fully-loaded metro bus driving by outside your house, or if you're so blessed, earthquakes.

Those are the tones you're trying to affect with the rumble filter. Some really good quality headphones will take you down that far. Koss Pro4AA will get you in the ballpark.

Waxy and Ignatz,
Thanks. "Snap-to" was the snafu.

First thanks for the tip sheet on recording from a reel to reel which is probably applicable to LP also.

I looked into this quite some time ago, the reason I select at sound board I did which I believe is capable of 192 KHz. The reason if one converts/changes formats/"recording media" between different "industrial standard sampling rates"-sampling frequencies (i.e. formats. ) one data/music will be can be distorted. This article was about the "next/future industrial music" standard sampling rate/frequency will be higher (i.e., what happens to the old formats if converted from a lower sampling rate/frequency to a higher one) .


I would suggest possibly original recording of the tape/LP be set at maximum frequency available, perhaps 192 KHz under an Linux OS I believed I was informed quite some time ago in regards to the sampling rate, then later it can be converted to a lower sampling rate format there would be least distortion than any other alternatives.

I could not find a reference to this when I searched. Converting music between sampling frequencies/sampling rates.
