about
nx_conv_transpose1d.nx -- BRICK 2 of the neural vocoder forward: transposed 1-D convolution (ConvTranspose1d),
the UPSAMPLER at the heart of HiFi-GAN's generator (4 stages upsample the 80-band mel to raw audio rate). Plus
leaky_relu (the activation every conv is wrapped in). Sovereign f32, same substrate as the FIXED Qwen forward.
ConvTranspose1d = the transpose/"scatter" of conv: each input sample spreads (weight * value) into a K-wide
output window at stride spacing. weight layout [C_in, C_out, K]. Known-answer tested byte-exact. license_tier: ORIGINAL expect_exit: 0
