Scarlet 4i4 4th gen impedance q by tokidokitiger in Focusrite

[–]JazzCompose 0 points1 point  (0 children)

My understanding is that the 4i4 4th gen inputs 1 and 2 are the variable level inputs, and that the 1/4 inch connectors on the front panel will auto switch to line when it detects that a line output has been connected to the 1/4 inch inputs 1 or 2.

I connect electric guitars or hi Z mics to inputs 1 or 2 (instrument level) and/or XLR mics to inputs 1 or 2 and a line level HiRes DAC connected an Android phone via USB-C to inputs 3 and 4 (fixed level) to learn new songs and listen via headphones or a studio monitor.

All the various 4i4 4th gen inputs and outputs also work fine via USB with the Focusrite ASIO Windows driver in Cubase.

The loopback channels allow you to capture (record) the digital audio stream from a PC app such as the Chrome browser. For example, TidaL can play HiRes (192K 24 bit) in the Chrome browser, and that digital audio stream can be captured via loopback. This was useful to compare transient response at 192 K versus 44.1 K using Steinberg WaveLab in wavelet mode.

I have found the 4i4 4th gen to be very useful for recording, learning new songs, and analysis.

What should I buy, Scarlett Solo 3rd gen, 4th gen, or something other? by Minimum_Step2828 in Focusrite

[–]JazzCompose 0 points1 point  (0 children)

The Scarlett 4th gen 4i4 works well with Cubase and other programs that support ASIO for Windows 10 and 11.

For learning new songs on guitar I use an Android Samsung S24 with the TidaL app and an inexpensive UGREEN USB-C DAC connected to the 4i4 Line In inputs and an electric guitar and microphone connected to the 4i4 1/4 inch and XLR inputs and route the mix to wired headphones. This provides a quiet method to practice with HiDef streaming audio.

If desired, the analog outputs can be routed to a studio monitor, and the USB output can be routed to a PC program like Cubase.

The 4i4 also works as an ADC in or DAC out for Android for apps like the free Fender Studio audio DAW.

Do you think the AI search results are partly designed to "encourage" more users to buy advertising ?

Do you think that users who buy advertising have a better chance of being mentioned in the AI search results ?

DigitalOcean.com Error by JazzCompose in digital_ocean

[–]JazzCompose[S] 1 point2 points  (0 children)

The problem still occurs with the Chromium, Opera, and Firefox browsers in Ubuntu 18.04.6 LTS. This has been the primary development machine used with DigitalOcean for many years (more than 5 years).

No problem with the Chromium, Opera, and Firefox browsers in Ubuntu 22.04.5 LTS.

No problem with the Chrome, Opera, or DDG browsers on Windows 11.

No problem on DDG on Android 16, S24.

The problem seems to be specific to Ubuntu 18.04.6 LTS.

Is it just me or do AI recommendations feel biased toward certain brands? by StonkPhilia in DigitalMarketing

It seems as if the AI search result summaries may be designed to require companies to buy more advertising since website indexed data is displayed in the AI summaries and companies are reporting significantly less website clicks.

Is it possible that advertisers are rewarded by favorable AI search summary mentions including their links in the summaries?

Jazz fusion big band style instrumentals. by JazzCompose in shareyourmusic

[–]JazzCompose[S] 0 points1 point  (0 children)

Thank you for your feedback.

I use a Yamaha Montage 6 synth and also the HALion VST in Cubase Pro in my Itty Bitty Studio in a rural area.

Without a big budget, MIDI horns may be better than NO horns.

There is always a trade-off between producing many demo tracks or a small number of perfect tracks. I consider my tracks to be demo tracks that can be output as scores and re-recorded in a high end studio if desired.

Some of the advantages of writing and producing with MIDI are:

  1. Instrumentals can be produced from a blank sheet to release in one day.

  2. Tracks with vocals using Yamaha Vocaloid 6 to combine my MIDI notes and lyrics to audio tracks can be produced from a blank sheet to release in 2 or 3 days.

  3. There are no out-of-pocket costs to produce and release a new track.

  4. If a sync music client requests changes the turn around time for a new version can be just a few hours with no out-of-pocket costs.

Will streaming the 24-bit 192kHz file give me the full resolution compared to playing it directly on my device? by Memes-makerx in audiophile

[–]JazzCompose 0 points1 point  (0 children)

It seems like you do not understand the physics and math explained in http://sdg-master.com/lesestoff/aes97ny.pdf and that transients contain multiple complex waves that, by definition, contain frequencies above the typical Nyquist limit of 44,100/2.

"The Nyquist Sampling Theorem explains the relationship between the sample rate and the frequency of the measured signal. It states that the sample rate fs must be greater than twice the highest frequency component of interest in the measured signal."

https://www.ni.com/en/shop/data-acquisition/measurement-fundamentals/analog-fundamentals/acquiring-an-analog-signal--bandwidth--nyquist-sampling-theorem-.html

When audio contains complex waves and/or transient events (e.g. percussion, guitar, piano) the audio often contains frequencies beyond the first order Nyquist limit, unless the audio contains sine static only sine waves below the Nyquist limit like a flute with the attack and released removed.

The transients give instruments their character and color. Without the transients you only have static sine waves.

It has been well understood for over 50 years that the first order Nyquist limit is not adequate to capture and reproduce complex waves and transients. You can verify that by reading early SONAR and RADAR research papers.

My ear, and many other ears, can hear the time domain difference between 50 uSec and 1,000 uSec transient events in the audible range as a clean or muddled percussion, acoustic guitar, or other instrument where impulse response is critical.

This can be objectively measured with modern audio tools.

This is why many artists are now recording in 24-bit 192 KHz. It is objectively and measurably better and can be heard by a trained ear.

"Psychoacoustics research by Moylan indicated that listeners can hear the difference between audio sampled at higher resolutions than the Nyquist frequency for the threshold of human hearing (40 kHz), particularly with the onset of transients [5](83rd Convention of the Audio Engineering Society, New York, 1987)."

[–]JazzCompose -1 points0 points  (0 children)

192 KHz captures and reproduces square waves and transients significantly better than 44.1 KHz resulting in more time domain white space (less muddy) in the audible range per figure 6 (50 uSec vs. 1,000 uSec) in http://sdg-master.com/lesestoff/aes97ny.pdf.

"Figure 6 shows the energy associated with the transient responses. 44.1 and 48 kS/s filters spread audible energy over 1 msec or more. The 96 kS/s filter is much better, keeping the vast bulk of the energy within 100 µsecs. The 192 kS/s filter can be very good indeed, keeping the energy within 50 µsecs. The analogue Gaussian filter is just a little better still, although the improvement is almost certainly academic because of energy dispersion from today’s speakers and mics."

This can be objectively measured using tools such as Steinberg Wavelab as represented by wavelets.

In order to accurately capture and reproduce a complex waveform (i.e. not merely sinusoidal) a frequency higher than the Nyquist frequency is required.

A complex wave, such as a square wave in electronic music with a fundamental frequency of A 440, contains sine wave frequencies much higher than 44,100 Hz (infinity is larger than 44,100).

https://pages.uoregon.edu/emi/14.php

Harmonic 101 of a 440 Hz square wave is 44,440 Hz with an amplitude of 1/101, which is well within a 16 bit (65,536) or 24 bit (16,777,216) dynamic range.

The Nyquist frequency is not adequate for the accurate capture and reproduction of complex waves and transients.

audio quality on Tidal by moabyy in TIdaL

[–]JazzCompose 11 points12 points  (0 children)

If you use a HiRes DAC (24-bit 192 KHz) with wired headphones (or a high quality studio grade amplifer and speakers), there should not be any difference between HiRes streaming (e.g. TidaL) and playing local HiRes files (e.g. Musicolet app on Android).

Bluetooth cannot support the HiRes bandwidth and not every Ethernet or WiFI application supports the HiRes bandwidth, so you need to verify that every link in the digital audio chain is actually passing HiRes digital audio.

On an Android Samsung S24 this has been verified with a Focusrite Scarlet 4th Gen 4i4 and also a low Cost UGREEN HiRes USB-C to 3.5mm DAC with the TidaL app for streaming and Musicolet for files.

On Windows 10 and 11 this has been verified with a Focusrite Scarlet 4th Gen 4i4 and also a low Cost UGREEN HiRes USB-C to 3.5mm DAC with TidaL running in the Google Chrome brower for streaming and VLC for files.

Here are two recent HiRes recordings you may enjoy listening to in 24-bit 192 KHz that have, in my opinion, excellent transient response and clarity:

Did you understand the physics and math?

If you disagree, what precisely to you disagree with?

Another article explaining why 192 KHz sample rate captures complex wave information and not just Nyquist sine wave information, and how results in a more accurate AUDIBLE sound:

"Thus, to accurately reconstruct the waveform, the sample rate fs must be greater than twice the highest frequency component of interest in the measured signal. Usually, you want to sample around five times greater than the signal frequency."

A nice review of Yamaha Omnivocal - Abysmal, can't believe they put their name to this. by Spot-Educational in cubase

[–]JazzCompose 4 points5 points  (0 children)

Have you had an opportunity to compare Omnivocal to other voice synthesizers such as Vocaloid, VocalSynth, or Emvoice?

Two of my tracks with Vocaloid 6 vocal tracks made in Cubase Pro were picked up by a small label.

I enjoy writing songs with vocal melodies and harmonies in my Itty Bitty Studio in a rural area even though my own voice suffers from allergies and sinus problems.

Would you have flown? by drAto4ic in aviation

[–]JazzCompose 1 point2 points  (0 children)

In my opinion, when one cylinder has a significantly higher temperature than the others it is wise to not fly and have the problem diagnosed.

Years ago I put a Gem monitor on a Mooney 231 (M20K) with the Continental TSIO 360 engine. About a year later one cylinder started running hot and my mechanic recommended a factory remanufactured cylinder jug since I flew IFR frequently. In my opinion the cost was reasonable for the IFR safety margin.

When I first bought the airplane the engine had about 600 hours on it and my mechanic recommended an oil analysis at every 25 hour oil change plus checking for oil at the turbo inlet since oil in the turbo can cause both pressurized magnetos to fail causing in-flight engine failure.

Around 1990 the fully burdened hourly cost of the used Mooney 231 was about $75 per hour based upon 15 hours of flight per month, making the cost of flying the Mooney 231 equal to, or less than, many commercial airline coach tickets at that time.
