![]() Streaming providers are rather reluctant to provide information on the respective data rates. Other audio formats used by streaming services are: ![]() The streaming giant Spotify uses this format. One example of this is the patent-free Ogg Vorbis format previously mentioned. However, there are other formats that play an important role in music reproduction today. More than 20 years after its invention, mp3 is still the most widely used audio format on the Internet. How high is the sound quality of music streaming services? A file encoded in AAC at 192 Kbps tends to deliver a better listening experience than an Ogg Vorbis file at the same data rate. There are also differences between the audio formats. Factors such as the music genre, the sound system and not least the individual listening, all play a role when it comes to evaluating the quality of an mp3 file. The file format alone therefore tells us little about the quality of the audio signal.īut there is no clear limit. Teufel Bluetooth speakers for Hi-Fi playbackĪn occasionally mentioned rule states that the loss of data for the auditory impression no longer matters from a bit rate of 192 Kbit/s. The higher the value, the lower the data loss compared to the source material. 64 Kbit/s as well as 128, 192, 256 or 320 Kbit/s can be implemented. They result from the respective bit rate, expressed in kilobits per second (“Kbit/s”). The true quality of mp3Ī general assessment of mp3 sound quality is complicated by the fact that there are different quality levels. 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. In order to limit the impact of data loss on mp3 quality, only information that is of little acoustic significance is ignored. Not everything that is captured in a recording gets into the compressed file. On the one hand through compression and on the other hand by omitting certain sound information. But how is the amount of data reduced compared to the original recording? So there still does have to be some file compression. Nowadays, the bandwidth of streaming and radio transmission via Bluetooth are limiting factors. At the time of its development, the storage capacity of hard disks was significantly lower than today, and the down- and upload rates were also insufficient for large amounts of data. Mp3 and other lossy audio formats such as AAC were developed with the aim of saving storage space, among other things. What “lossy” means in terms of sound quality In this article, we discuss the technical quality of mp3 and how it compares to the sound quality of other formats. After all, there is no uniform standard for mp3 quality. However, we shouldn’t be so quick to dismiss mp3 altogether. The accusation is not completely unfounded, because mp3 is a lossy format. Hi-Fi purists claim that many people no longer know what good sound actually is because of mp3. When it comes to “mp3 and sound quality” you might feel as though you are treading on a minefield.
