DESCRIPTION:
In this video, I improve the acoustics in my little studio by removing the old carpet. I used to think that carpet would help the acoustics but I was wrong. Auralex designed the layout of my studio years ago. It is a spare room in my house. I needed to replaced the old, thrashed carpet in the room. I Googled what flooring would be best in a studio and this is the first thing I found and it was coincidentally from Auralex:

"This might be a little counterintuitive, but hard flooring is the best for most studio applications. Why are hard floors better? Here are a few reasons:

The sound of hard floors is more ”natural.” In recording rooms, this results in a better performance from musicians because they are more comfortable. In control rooms, the hard floors provide a reflective surface that can balance nicely with the absorptive and diffusive treatments on the walls and ceiling.

Carpet acts as a low-pass filter. This can cause the room to sound ”boomy” before treatments. Because the low frequency artifacts are more obvious, low frequency treatments, such as LENRD or Venus Bass Traps, may not appear to work as well.

Floor reflections are ”rejected” by the ear-brain mechanism. Therefore, they are not going to affect critical listening like wall and ceiling reflections do. There are many, many professional studios, built by folks with ”golden ears.” They all swear by hard floors in the control room.

Rooms with hard floors do not require any additional treatments versus carpeted rooms. I.e., this is not an attempt by us to make your room more reflective in order to sell you more treatments. Whether you go with hard flooring or carpet, you will need the same amount of LENRDs, Studiofoam, T’Fusors, etc. The rooms with hard floors will simply respond better with the added treatments.

What kind of hard flooring works? Hardwoods, parquet, tile (vinyl or ceramic), laminate, bare concrete and even linoleum are all acceptable. It is usually best to choose the flooring that fits your budget and your ”vibe.” "

This concrete definitely fit my budget. All it cost me was a few hours of sweat. I do a little sound test with some classic vinyl from Peter Gabriel and SRV. The true test will be when I crank the amps up. I'll do that in the next video.
