24-bit WAV, 800 MB batches and fair limits

One update covering both the things that got in the way and the things you asked for.

• 24-bit WAV export is here. That is the master format for distribution: processing always ran in 32-bit float, but export stepped down to 16-bit with dithering. Now you can take the result without that step. 16-bit stays the default — the file is one and a half times smaller, and on a finished master the two are indistinguishable by ear. Why 24-bit matters anyway, and when you actually need it, is covered in a new blog post, "16 vs 24 bit: which master to deliver".

• Batch processing grew from 240 to 800 MB in total. The old budget was chosen around a proxy limit that has not been there for a while — we re-measured and raised it. We also fixed the pricing table: it claimed Free and Pro had no batch at all, while Free gets 10 files and Pro and Studio get 50 each. The app now shows both the file count and the space used before you upload, instead of failing afterwards.

• A failure on our side no longer eats your attempt. The daily counter counted every run, so a failed master took a whole day away on the free tier: the token came back, the day did not. Now only successful and running jobs count, and guests get their monthly attempt back.

• The blog and news pages work on a phone. On a narrow screen the header hid its links, and the burger menu had never been wired into those pages — the logo was the only way out. Fixed.

• Buttons are readable again. White text on the light half of the gradient measured 3.96 contrast against a 4.5 standard, so the label disappeared. We recalculated and fixed 56 buttons across the site: landing, pricing, wallet, sign-in, referral programme.

• Limit and sign-in protection hardened: a client address can no longer be spoofed with a request header.

Thanks to everyone who writes in about rough edges — half of this list came from your messages.
