@ -49,7 +49,7 @@ The following can be used in place of `(value)` for `(key) = (value)` commands.
* `$1|2|3|4`: value has size of 8/16/24/32 bit (optional, defaults to 4)
* Example: `@0x10:BE$2` means `get big endian 16b value at 0x10`
- `(field)`: uses current value of some fields. Accepted strings:
- `interleave, interleave_last, channels, sample_rate, start_offset, data_size, num_samples, loop_start_sample, loop_end_sample, subsong_count, subsong_offset, subfile_offset, subfile_size, name_valueX`
- `interleave, interleave_last, channels, sample_rate, start_offset, data_size, num_samples, loop_start_sample, loop_end_sample, subsong_count, subsong_offset, subfile_offset, subfile_size, base_offset, name_valueX`
- `(other)`: other special values for certain keys, described per key

### Base offset chaining
Some formats read an offset to another part of the file, then another offset, then other, etc.
You can simulate this chaining multiple `base_offset`
```
base_offset = @0x10 #sets at 0x1000
channels = @0x04 #reads at 0x1004
base_offset = base_offset + @0x10 #sets at 0x1000 + 0x200 = 0x1200
sample_rate = @0x04 #reads at 0x1204
...
```
