At least on my end I can't see an attachment. Since FM broadcast stations are regularly spaced the polyphase filterbank is a good choice for separating out each of the individual channels. You can then use the same demodulation set of blocks and file sink that you're (presumably) using now to handle each channel.

Thanks for this great software. We are tinkering with a setup for listening to radio and storing the streams as wavs. We have two challenges that we haven't been able to tackle satisfactorily. Any help would be appreciated.
1. What do we need in order to tune into as many stations as an rtlsdr can fit in its bandwidth and create wav files for each one. In our setup we use each sdr for a single station but scaling is a challenge.
2. How can we optimize our existing flowchart ( included screenshot) for broadcasting wavs from the computer thru a hackRF. We use this for testing the sdr setup.
Thanks all,
Luis
