Well done, finaly u done it. :) ps, you can extent the range to full 26kHz if you connect the sound card with 96khz. the sound cards with 48kHz have limited range for this program. Have a check if your sound card can do the 96kHz output.
Ok, one question to community here....I am enjoying in measuring different decks, but in one...Telefunken CC20 with HIGHCOM nrs(excellent) I have demonstration original Telefunken recorded tape, for HIGHCOM functionality...when I engage HIGHCOM on that tape, sound becomes dull, almost without HF. On the other hand, when I am recording with highcom on, sound is very nice, dynamic is awesome. Screws of head are intact, there is paint on them. What can be the cause of dull original demonstrations tape? Btw, azimuth is compared with 3 other decks, it's good.
Thank you for a very insightful video. But here is a general question from a total noob. Are there t-100 libraries with factory values for different cassette decks, like Nakamichi Dragon, C7...Pioneer CT-1250, 1000, 850, etc. that can ne preloaded and against which measurement and calibration of the repaired/restored units would be made? Or at least are there downloadable libraries in communities from T-100 users who have performed restorations as close as possible to factory values?
Please correct me if I am wrong.. 🙏 I can see that when you go into 20kHz (2.40 min time in above video) level dropped 1dB and also when you go below 400Hz, level dropped significantly. I believe this is because of the enteral ADC that you are using for this measurements. By the way I am using Scarlett 2i2 and never drop levels even at 20Hz or 20KHz. I cannot post images here, but I tested few times including at -20dB and as well as 0dB..!
You need a reference Dolby level tape and a millivolt meter or an oscilloscope. If it's a two head deck a function generator app might do the job as reference signal source, just to balance the channels. Even radio static could be a good enough source... Still if you want to be precise you need a reference tape to make sure the REC balance is consistent with the PB.
Playback level calibration tapes are almost always recorded with a 315 Hz test tone, but you’d need to record said tape on a deck that you are absolute certain is perfectly in balance, has factory spec speed, and factory spec wow and flutter. And no - you don’t need a Dolby labs test tape for just balancing playback levels.
I am surprised about this discussion. Without a reference tape you can't know if you're recording one channel hotter than the other and playing it back weaker than the other, this results in a perfectly balanced condition within the deck itself. This chance is mitigated when a two head deck is involved as the head is less selective on HF reading and less performing on recording.
When you’re cleaning and lubing a transport to lower w&f, are you using lubricants listed in the service manual or do you have a set of more universal lubricants that you prefer?
Great video as always. At what level did you set the master rec level knob of the DR-10 to do this calibration?
First! Just bought the t-100, this will be very useful to me
It’s fantastic software and the developer (Chen) is a very nice guy. Always quick to respond to feature requests and support.
@@EnochLight Please tell me how to contact the author of the program, I can't install it through the Microsoft Store because in Russia.

Thank you so much for the detailed tutorial! At what level did you set the master rec level on the cassette, and how does the affect the process?
Are you still using your frequency counter + AC voltmeter, like in your earlier videos, or does T-100 replace that functionality?
Yes, I use it. In many cases, it is more convenient for me.

@@colloidalsilverwater15ppm88 looks like your tape maybe from Nakamichi. They been producing high comm NR themselves
@@hifirulezzz no. Tape is Telefunken. Probably tape loses some quality during 43 years.....

Nope, that is not possible.
Unbelievable! Cassette deck recording till 18kHz on 0 dB! Wow!

It is ok, better card is more precise, but we are in analog world, 1 db here and there is not a huge problem.
@@hifirulezzz Thank you for the reply.. By the way, greatly appreciate your all videos..!!!
I am leaning many new things from your videos.!
@@kasunjayasena Thanks!
@hifirulezzz can you inform me what name & model of Line in port connect to your MacBook ?
Today I am using Scarlett 2i2 interface, before I used simple $20 interface from Amazon.
What is the best way to make my own calibration tape in order to balance left and right channels?
If you have deck you trust and with factory sealed head screws, than you have a chance.
You need a reference Dolby level tape and a millivolt meter or an oscilloscope.

@@m80116 Only if you use Dolby....

I am using silicon lubricant for the moving parts and oil for sewing machines for the bearings.
@@hifirulezzz right on. Do you have a favorite brand that you prefer?
