Join Bill Gibson for an in-depth discussion in this video About the example files, part of Microphone Techniques: Essentials.
- [Instructor] I'm a big believer in the value of high resolution audio, typically understood to be 48 kilohertz, 24-bit, or better. 96 kilohertz, 24-bit audio has become the standard in the community of respected audio professionals. Many of the audio examples in this course are available as accompanying high-res 96.4 WAV files. These files let you hear the real impact of the mics and techniques being used. Just download them and follow along through this course. We've provided support files for three videos. Included are the 96/24 source files, but also 48/24, 44.1/16, and 256 and 128 kilobit per second MP3s so that you can compare the differences in sonic quality that each format offers. To hear the differences, make sure that your interface is set to 96/24 so that you know you're hearing the full audio quality. Depending on your operating system, you can probably highlight an audio file and then press the space bar to hear the audio. To easily A-B the quality differences, import all versions of the same audio recording into a 96/24 DAW session. Even though the DAW is likely to up-sample everything to 96/24, each file already has the deficiencies and limitations baked in. So you can still solo each track to hear the differences. A controller like this Presonus Faderport 16 really makes it a lot easier to make these kinds of comparisons. (gentle music) Notice on this analyzer that the 96/24 files have content all the way up in the 40 plus kilohertz range. (light music) But the 128 kilobit per second MP3s obviously filter out the highs. Notice the difference on the analyzer as I solo the different versions. (gentle music) It's interesting to see the differences in these files. But if you listen closely, you'll soon hear a wide range of differences between high-res files, CD quality files, and MP3s.
