I guess this has only come about since I started audio engineering, and learnt and discovered a lot about sound from listening.
The sound quality debate is however subjective. How you listen to your music, and how you enjoy it is up to you. If you like how something sounds, that is all that matters, and I would ask you to always sit back first and foremost and enjoy the music you listen to.
I thought I would back up my argument that MP3s are awful horrible things, with facts. I can hear this on high end studio monitors. I took it upon myself to help train his ears, and now, he can also hear the difference and has become just as passionate about the subject as I have. I have to thank him for letting me use that as a primary example. We have gone on to train our ears to hear a lot more things. In order to hear the differences, you need to know what a MP3 sound is, to distingush between an MP3 and the lossless file formats.
Fact 1. So there still does have to be some file compression. But how is the amount of data reduced compared to the original recording? On the one hand through compression and on the other hand by omitting certain sound information.
Not everything that is captured in a recording gets into the compressed file. In order to limit the impact of data loss on mp3 quality, only information that is of little acoustic significance is ignored. More precisely: the frequencies of particularly low and particularly high tones are cut out, since people can only perceive extremely high and low frequencies to a limited extent or even not at all.
A general assessment of mp3 sound quality is complicated by the fact that there are different quality levels. All the sources mentioned are at 16 bit. But there are audio files that are at 24 Bit. There has been much debate about whether the difference between the two is really that important.
To understand the battle between 24 Bit and 16 Bit we need to cover how sound functions and more importantly how we hear that sound. Audio bitrate is usually the primary way to determine the sound quality of files but there is more to it than meets the eye….. Bitrate is determined by the sampling rate and the bit depth. The sampling rate is the number of samples taken in a second. For example, CDs have a sampling rate of This all stems from the groundwork laid out in the Nyquist—Shannon theorem.
This theorem determined that if you double the maximum frequency of the source you can accurately capture the sample. The human hearing range tops out at about 20kHz.
Nothing that you would realistically hear. Hi-resolution audio can be recorded at double the standard CD rate or even as high as kHz. The question often comes up if this is needed. There are instances where a higher sampling rate does help to improve the listening experience. Analog to digital converters have an in-built low pass filter.
This filter processes out frequencies that are not within the sampling limit. For example, if the sampling rate is Anything above that will introduce fake samples which is where the low-pass filter kicks in to process them out. By increasing the sampling rate you move the low-pass filter higher into the frequency range. This moves it further from our hearing range resulting in cleaner sounding audio. The second component is bit depth. Bit depth is the number of bits available to capture sound.
For each extra bit beyond the first the accuracy and number of bits doubles. Each bit is a slice of the sound you are hearing. The more bits available the greater options in the information that can be stored. The end result is greater accuracy in hearing subtle details which might be lost at lower bit depth. With bit audio, there are 65, possible levels that can be captured.
To help visualize the difference imagine if you were watching a movie and you only got to see every 10th second of the image.
You would still be able to get an idea of what was going on but you would miss out on the subtle changes in the movement of the actors on screen. If you then got to watch every 3rd second you would have a greater sense of their movement.
Bit depth works the same way allowing more refined detail to be captured. Read our buying guides for:. When it comes to audio bitrate size does matter. The more kilobits per second the greater the quality of the sound. For most general listening kbps is ideal. Of course, CD-quality audio that stretches to 1,kbps will sound better. To determine the best audio bitrate you need to also assess your needs. If storage space is a concern high bitrate files will rapidly eat into your available space.
For example, an MP3 file at kbps will take up approximately 1mb of space per minute of audio. A kbps MP3 file will take up about 2. Meanwhile uncompressed CD audio will take about If you have space go for the highest quality bitrate possible. You can always convert down to smaller files sizes but there is no way to convert back up to higher quality. There are situations where higher bitrates are not ideal. Streaming services like Spotify need to be able to deliver data efficiently without lag or delay.
As a result, many streaming services have lower bitrate audio quality. YouTube audio streams AAC files at kbps. Lower audio bitrates achieve smaller file sizes by compressing the source file. Higher quality audio bitrates result in much higher file sizes. Unfortunately, this compression also results in a loss of quality. The images below highlights the audio frequency cut off point for a kbps MP3 compared to a kps file.
The lower the bitrate of an MP3 the more data is removed from the source. All these graphs and waveforms images do not compare to the real thing. At the end of the day, the true judge of quality is our own ears.
Quality is also affected by what you are listening to the sound on. Budget DJ speakers will also produce poor quality audio even with the best bitrates. Invest in quality DJ speakers if you want the best results. Even a pair of high-quality studio monitors can make a huge difference when it comes to your perception and understanding of audio quality. Have a listen for yourself and see if you can hear the differences.
High Quality MP3 File — kbps. Low Quality MP3 File — kbps. As technology continues to improve, so does the potential to deliver better quality audio.
Even streaming services like Spotify that have relied on smaller bitrates are now offering higher quality audio. The term hi-resolution or HD audio gets thrown around a lot but what does it actually offer?
