Why is the MP3-quality improvement difficult?
In the case of MP3, it is the effective implementation of the psycho-acoustic findings from the 1960s: Loud sounds can mask quieter sounds, so obscure, if you are at the same time, shortly before or shortly after included in the sound signal. Especially low frequencies can mask higher frequencies. MP3 detected masked spectral components and store them with a lower accuracy. This accuracy loss is irreversible:
- If you have WAV or AIFF to MP3 convert caused artefacts, because MP3 is a lossy Codec.
- In some of the practice tips we will explain in Detail what is MP3 and what you think of Audio CD and FLAC is different.
- MP3 saves the dynamics of some frequencies with low accuracy. It can also arise from noisy Events noise.
- This error should be masked, so inaudible, be. If not, it will not disappear, you unfortunately, if you save the MP3 with a higher Bitrate, or WAV convert.
- If you are good MP3 quality is important, pay attention to the ideal settings in the MP3 Encoder , and on the most appropriate Sample Rate.
- It is particularly difficult, if you want to convert a Mono file to Stereo. In this case, you have to guess the Stereo-Information of each frequency at each time point. A virtually impossible task.
- You want no loss of quality, do you prefer FLAC or ALAC.
So, you can improve the MP3 quality
If you still have the Original file, you should encode according to the above-linked manual, the MP3 new. Otherwise, you have the following options, bad MP3 the Sounds something to improve:
- In the majority of Audio players you can weight by means of the Equalizer, the frequency spectrum according to your needs. We will show you a practical tip how to use an Equalizer to be set optimally.
- For many people means a louder far better. When you apply a compressor or even a Multi-Band compressor, you can increase the perceived volume of your music clearly.
- Both effects can, for example, in Foobar with a PlugIn called "Effect DSP" apply.
- With the help of our practical tips you can use in Audacity, you free CHIP, get mains hum removal and noise eliminating , and generally bad Sound restore.
- We offer you a comfortable entry into Audacity.
If you have small file sizes and good sound quality like you are with the AAC Format, well-advised, because AAC sounds better than an equivalent MP3.
