<h1>Abstract</h1>
</center>
<tr>
<td style="text-align: justify;">
Apollo is a novel music restoration method designed to address distortions and artefacts caused by audio
codecs, especially at low bitrates. Operating in the frequency domain, <a
style="background-color:LightYellow;color:red">Apollo uses a frequency band-split module,
band-sequence modeling, and frequency band reconstruction to restore the audio quality of
MP3-compressed music</a>. It divides the spectrogram into sub-bands, extracts gain-shape
representations, and models both sub-band and temporal information for high-quality audio recovery.
Trained with a Generative Adversarial Network (GAN), <a style="color:blue;">Apollo outperforms existing
SR-GAN models on the MUSDB18-HQ and MoisesDB datasets</a>, excelling in complex multi-instrument and
vocal scenarios, while maintaining efficiency.
