* Add methods to "map" a buffer's storageChris Robinson2018-01-204-12/+137
| | | | | | | | | | | | | | | | | | | | | | Requires the MAP_READ_BIT or MAP_WRITE_BIT flags to be OR'd with the format upon a call to alBufferData, to enable mappable storage for the given access types. This will fail if the format requires internal conversion and doesn't resemble the original input data, so the app can be guaranteed the size, type, and layout of the original data is the same as what's in storage. Then alMapBufferSOFT may be called with appropriate bit flags to get a readable and/or writable pointer to the buffer's sample storage. alUnmapBufferSOFT must be called when access is finished. It is currently invalid to map a buffer that is attached to a source, or to attach a buffer to a source that is currently mapped. This restriction may be eased in the future, at least to allow read- only access while in use (perhaps also to allow writing, if coherency can be achieved). Currently the access flags occupy the upper 8 bits of a 32-bit bitfield to avoid clashing with format enum values, which don't use more than 16 or 17 bits. This means any future formats are limited to 24-bit enum values, and also means only 8 flags are possible when declaring storage. The alternative would be to add a new function (alBufferStorage?) with a separate flags parameter.

* Store mulaw and alaw samples directly in the bufferChris Robinson2018-01-175-35/+40
| | | | | | | They're now decompressed on the fly in the mixer. This is not a significant performance issue given that it only needs a 512-byte lookup table, and the buffer stores half as much data (it may actually be faster, requiring less overall memory).

* Replace some freq_mult variable names with f0normChris Robinson2018-01-136-35/+53
| | | | | | The latter is a bit more descriptive as f0 is often used to denote the reference frequency of a filter, so f0norm indicates the normalized reference frequency (ref_freq / sample_rate).
