Its paper reports real-time synthesis speed on specified CPU and GPU hardware; those measurements do not imply embedded-device or production suitability.
MelGAN, introduced by Kumar et al. in 2019, is a non-autoregressive, fully convolutional GAN for conditional waveform synthesis. Its generator upsamples a mel-spectrogram through transposed convolutions, with residual blocks using dilated convolutions. The paper uses multi-scale waveform discriminators and a feature-matching loss to train the generator. It reports qualitative demonstrations in speech synthesis, music-domain translation, and unconditional music synthesis, and uses Mean Opinion Score as a subjective evaluation measure. The authors report that their PyTorch implementation ran at over 100 times real time on a GTX 1080 Ti GPU and over twice real time on CPU without hardware-specific optimizations. These measurements apply to the reported implementation and hardware, not to every deployment or device.
Reproduce the paper’s mel-spectrogram inversion experiment and compare generated waveform quality.
Use the paper’s speech-synthesis and music-domain demonstrations as separate research tasks.
Report mean opinion score when comparing listening quality under the same evaluation conditions.
Measure latency on the target CPU or GPU rather than inferring deployment speed from a different device.
MelGAN provides a research example of non-autoregressive GAN-based waveform synthesis. For a current application, compare audio quality and latency against alternative vocoders on the target data and hardware; the cited paper alone does not establish suitability for mobile, embedded, or streaming deployments.

MelGAN adalah vocoder: ia mengambil representasi fitur akustik, mel-spektogram, dan mensintesis bentuk gelombang yang sesuai.
WaveNet menghasilkan sampel satu per satu secara otomatis; Generator konvolusional MelGAN menghasilkan seluruh bentuk gelombang dalam satu lintasan maju paralel.
MelGAN menggunakan beberapa diskriminator identik yang memeriksa bentuk gelombang asli dan versi downsampling untuk menangkap struktur pada skala berbeda.
Hilangnya pencocokan fitur meminimalkan jarak L1 antara peta fitur diskriminator untuk audio nyata dan audio yang dihasilkan, memandu generator dan menstabilkan pelatihan.
Blok sisa dengan konvolusi melebar memperluas bidang reseptif secara efisien, memungkinkan generator memodelkan struktur temporal jangka panjang.
