?? hi res recording studio practices

Studios don't offer recordings. They make them. That's why they're called recording studio's. Record labels don't make recordings, they offer them for sale. The seller puts their label on the record. That's why they're called record labels. The recordings are actually made by the producer, that's the guy who brings the performing and recording talent together with the money to make and sell the resulting recording. This guy produces it, which is why he's called the producer.  

In terms of the recording process itself, exactly how all that is done is determined by the recording engineer. This is the guy who runs the microphones, mixer, and all the other recording equipment. A lot of them modify their equipment, and some of them even build it. That's what makes them recording engineers.

Once the recording itself is made, its usually at this point a raw tape of multiple tracks. It still needs to be mastered, that is converted into a final form suitable for transfer to CD, LP, or what have you. This is the job of the mastering engineer.

The end result of this process is an original master tape. The original master thus represents a tremendous amount of time and money and makes people nervous having so much at risk and so usually the first thing done with the original master is to make copies. So its always a master tape used for pressing CD or LP, but its not always the original master tape.

That's the basic process. But there's a million variations. Artists, producers, and label execs can interject and influence it at any point. Jennifer Warnes Famous Blue Raincoat, for example, was recorded all digital. But then in mastering four versions were made. Same mix, same everything, just mastered differently. One of the masters was to analog tape. The talent (Warnes and Cohen) and the producers all agreed the analog sounded best. So the analog master was used, both for CD and LP.

If you've read this far then it should be clear there is no answer to your question. Its not the studio, and its not consistent. Your question cannot be answered the way its asked. It can only be answered with respect to particular individual recordings. And maybe not even then. (But watch these guys try!)😂😂

Wrong again.

Patience, grasshopper.

Most recordings made in the last 30 - 40 years have been recorded digitally, that means no tape used. It was recorded to a hard drive or some other type of digital storage.

I’d guess that early on, when digital storage was more expensive, recordings were mostly made at a sampling rate of 44.1khz or 48khz and a bit depth of 16. CD quality, in other words

Now that digital storage is cheaper and more compact, and streaming bandwidth is wider, many recordings are made at higher sampling rates and bit depths, 96/24 192/24. Sometimes DSD recordings are made.

If tape was used to record a new album, that will usually be noted on the sleeve, the booklet (for digital discs) or in the advertising because recording to tape is not the norm anymore.

It is very hard to find out at exactly what sample rate and bit depth a digital recording was made. For some reason the record labels like to keep that information secret. Download sellers like HDtracks sell downloads of the same recording at different sample rates and bit depths, but, in the past, when they have been asked at what sample rate/bit depth the recording was made, they have said they don’t know, they just get the files from the record label without that information.
