| 7 | Large file support is now available on many systems by running configure |
|---|
| 8 | with the flag --enable-largefile. By default support for large files |
|---|
| 9 | is turned off. This option is unnecessary on systems where off_t is |
|---|
| 10 | always 64 bits (e.g. IRIX, FreeBSD, NetBSD, OpenBSD, Mac OS X). |
|---|
| 11 | |
|---|
| 12 | The Audio File Library supports CCITT G.711 mu-law and A-law as well |
|---|
| 13 | as IMA and MS ADPCM. Many compressed data formats are not supported. |
|---|
| 14 | This is currently the most important issue to address. |
|---|
| 15 | |
|---|
| 16 | Error handling is at the present quite robust, but more work can always |
|---|
| 17 | be done in this area. |
|---|
| 18 | |
|---|
| 19 | SGI's Audio File Library on IRIX implements the following formats which |
|---|
| 20 | this version of the library does not: |
|---|
| 21 | |
|---|
| 22 | MPEG1 audio bitstream |
|---|
| 23 | Sound Designer II |
|---|
| 24 | Audio Visual Research |
|---|
| 25 | Amiga IFF/8SVX |
|---|
| 26 | SampleVision |
|---|
| 27 | VOC |
|---|
| 28 | SoundFont2 |
|---|
| 29 | |
|---|
| 30 | I plan to implement some of these as time permits. Sound Designer |
|---|
| 31 | II is out of the question because of its dependency upon Macintosh |
|---|
| 32 | resource forks. Handling these files on Unix systems is simply not |
|---|
| 33 | worth the effort. |

| 37 | This version of the Audio File Library has been tested under the |
|---|
| 38 | following operating environments: |
|---|
| 39 | |
|---|
| 40 | mips-sgi-irix6.5 / IRIX 6.5 (MIPSpro cc 7.4m) |
|---|
| 41 | powerpc-apple-darwin7.2.0 / Mac OS X 10.3.2 (gcc 3.3) |
|---|
| 42 | i686-pc-linux-gnu / Debian GNU/Linux 3.0 (gcc 2.95.4) |
|---|
| 43 | sparc-sun-solaris2.8 / Solaris 8 (gcc 3.0.4) |
