bitpack¶
A variable-width bit-packing transform on quantized m/z values. Reads the needed bit width from the data instead of using a fixed 16/24/32 split.
- Target stream: m/z
- Loss: Yes — quantization controlled by

When to use it¶
When you've characterized the precision of your data well enough to be
confident in a custom scale factor and want better ratios than fixed-width
delta encoding. Less predictable in compression ratio than the delta*
family but can outperform them on certain instruments.
