Hello,
For sending audio efficiently over OSC I would need an OSC-"BLOB". Unfortunately the packOSC object supports no OSC-"BLOB"s. Is there any possibility to send BLOBs?
since blob is an arbitrary type, you have to interpret/generate this list of bytes somehow in your patch. if you are working that low-level, i guess you can also de/construct OSC-packages on your own.

I can probably add a Blob type to [packOSC] and [unpackOSC]. The thing is that the blob type is supposed to consist of arbitrary bytes (8-bits), but Pd audio works with 32-bit floats. There is nothing [unpackOSC] can do with a received blob except output the list of bytes, so some other object would be needed to pack groups of 4 bytes into floats again. It may end up being just as efficient to send a bunch of floats for each signal vector.
iirc, for the very project the decoding is done outside of Pd anyhow (on specialized hardware), so the problem of [unpackOSC] not knowing what to do with a blob is a minor issue here. (and the use of specialized hardware is the reason why data (low-resolution fixed-point numbers) should actually be packed in a blob rather than floating-point).
i still think (see above) that even [packOSC] cannot provide a consistent interface to pack blobs into an osc message that is sufficiently more simple to use than manually constructing OSC messages.
