Array Low Bit Rate DAB Plus.sts [181.13 KiB]

I've created this preset for use with low bit rate DAB+ in mind.
It was used and tweaked on air for a DAB+ trial station (alternative rock/pop music) at 48kbps and 32kbps stereo HE-AAC v2/v1 at 48k sample rate.
It's set to peak at -4dBfs (on the post amplifier level) to allow overs which are inherit to the AAC+ encoding process which I'd recommend keeping to preserve the best audio quality in the high frequencies. Avoid setting this above -1.5dB for AAC+ if you really do need it extra loud.
The processing is probably a bit lighter than some, with the less is more mindset for these low bit rates and to avoid too much clipping, but there's still some nice compression and AGC to even out levels and give it that processed 'radio' sound.
There's some EQ which calms down the 8k region and does the usual boost in the low end and presence boost in the mid range and very high frequencies for a bit of extra 'sparkle'.
Let me know what you think.
