Bit Depth or Sample Rate: Do they affect loudness measurements?

bit depth and loudness

In the digital audio world, bit depth and sample rate are the primary factors involving sound quality. Bit depth directly correlates to how many “levels” of volume can exist in a recorded audio file. The greater the bit depth, the more variety in volume levels. For example, if we theoretically had two bits for our bit depth, we could think of volume values as “quiet” and “loud”. If we had four bits, we could think of it as “quietest, quiet, loud, loudest”, so on and so forth. When we record at a greater bit depth, we can reproduce volumes in a more realistic way.

Tips for Professionalism and Client Interaction

The music industry is a customer service driven business. If you want to make money recording music, most of the time you are going to be working with other people. While having good mixing skills and recording chops are great, when it comes down to it people expect to be treated a certain way, and they expect to get a certain level of professionalism.

Having good client interactions can really help build a level of trust and generate more business. Many people like studios that have fancy equipment and the best engineers, but when it comes down to it, if they aren’t treated well or they feel that their needs are being put to the way-side, they probably won’t want to come back, no matter how expensive the gear in the studio is.

Sound City Movie Night

CRAS takes a field trip to see the new Sound City documentary!

The Conservatory of Recording Arts and Sciences is more than just your average audio engineering school. Students are only required to spend an average of 20 hours a week doing the curriculum, but we are open 24 hours a day, seven days a week. Outside of normal class hours there are always a ton of things going on, whether it’s a recording or mix session, study groups, mic builds, or even in this case, movie nights!

Everything You Wanted to Know About a Mic Cable

While most of the modern world is moving towards a completely wireless society, the audio industry has firm roots in the wired-world. Images like the one below are a very common sight for the busy audio engineer.

Even though there are plenty of wireless mics and devices that get used in live sound, or even in the studio, you will get the best fidelity and the least hassles from going with a wired source. Even wireless mics have to be wired into a source at some point. So how exactly does a cable work?

cable nightmare

Fundamentally, a microphone is a transducer, that converts air pressure to electronic signal. That electronic signal needs to be moved through a pre-amplifier, and then it can be processed and mixed as audio. Since that is the basic principle of audio recording, we spend a lot of time at CRAS talking about how electricity works, especially when it comes to routing signal, signal flow, microphones and mic cables. We spend several classes in the Analog Recording and Troubleshooting & Maintenance curriculum explaining how all this works! Our classes even get down to the science of how resistance works, how to calculate voltage requirements, and how circuits work.
