1 has worked for me in the past ..you may need to generate more samples using various techniques like add a small noise in audio then taking its spectrogram,cut - mix a random portion of spectrograms, etc..

Thank you u/shadow_fax1024. Did you use a RNN or a plain CNN? Did you also had that long audio files (40min - 60min)? I'm not sure about how such long audio files can be used in a RNN.
