In this section, we provide reconstruction results from each domain with the intent of illustrating the impact of quantizer dropout. Additionally, we present an animation below that depicts the spectrogram of the reconstructed samples at varying bitrates. Each row corresponds to a different model trained with the labelled dropout rate.

Spectrogram of reconstructed audio with increasing number of quantizers. Each row corresponds to a different model trained with the labelled quantizer-dropout rate. Samples chosen here belong to the first columns of the respective domains in the audio section below.

We present reconstructed audio samples from models trained with different quantizer dropout rate. The reconstructions are computed at full bandwidth (8 kbps).
