Most people will be able to determine that a 96kbps file sounds poorer than most other bitrates. That’s indicative of a 96kbps file, as that is where they cut off. For many audiophiles, there is little substitute to totally lossless audio.įinally, take a look at this track. There are meant to be exceptions, but since there are only a few standard encoders, this applies for the most part.įLAC files don’t lose any of their higher frequencies, hence being known as a “lossless” file type. The chart is for a track that is in 320kbps. 320kbps cuts off at 20kHz, as shown below. When you do that, the MP3 Encoder dialog box appears. Higher bitrates preserve higher frequencies. For example, if you want to play certain songs on a portable MP3 player, you might want to use. At the bottom is the running time of the track to the right is the track’s volume, and most importantly the frequency displayed on the left.Įssentially, bitrates work with frequency. zip we explained the appeal of these programs previously.ĭrag a file into the window for Spek, and wait a few moments as it draws a chart. Spek is available as a portable file in a. Others exist, but we chose Spek based on its cross-platform compatibility and free nature. How do you sort the wheat from the chaff?īegin by downloading Spek, which is an acoustic spectrum analyser.
