The only exception to this is the case of RAW files where the caller has to set the samplerate, channels and format fields to valid values. The library seamlessly converts between the two formats on-the-fly. The error message is also correct, as we are using an unfittingly configured sndfile. The currently understood formats are listed in sndfile. Sign up using Email and Password.

Sndfi,e, since maintaining the documentation is the least fun part of working on libsndfile, these docs can and do fall behind the behaviour of the library. The currently understood formats are listed in sndfile. The number of bytes read or written must always be an integer multiple of the number of channels multiplied by the number of bytes required to represent one sample from one channel.
The file write items functions write the data in the array pointed to by ptr to the file. I haven't figured out any of the solutions yet but as soon as I do and confirm they work I'll mark it as accepted, thank you very much for the detailed and extremely helpful answer. For items-count functions, the items parameter specifies the size of the array and must be an integer product of the number of channels or an error will occur.
Regardless of whether data in the file is 8, 16, 24 or 32 bit wide, the data will be read as floating point data in the range [ When opening a file for write, the caller must fill in structure members samplerate, channels, and format.
You need to define and name the types only once in an include file created for that purpose.
After successful set up and launching the program without errors, I tried to generate sound via one of the examples, " play osc 60 ", and was met with this error:. Active 9 months ago. Sign up using Email and Password.
For the items-count functions, the items parameter must be snfile integer product of the number of channels or an error will occur.
The file seek functions work much like lseek in unistd. As with the read functions abovethe only difference in the items and frames version of each write function is the units in which the buffer size is specified. I was shocked to get any help at all on sndfioe, let alone such quick, detailed and sufficiently verbose help.

After successful set up and launching the program without errors, I tried to generate sound via one of the examples, " play sndcile 60 ", and was met with this error: Again, the data type used by the calling program and the data format of the file do not need to be the same Note 1. This may or may not work depending on whether your system supports it and it is not a clean solution as there may be additional misconfiguration of libsndfile going unnoticed.
I see, thank you for the syntax correction. I am going to use the functions and data structures provided by sndfile.

It is important to note that endfile data type used by the calling program and the data format of the file do not need to be the same. Asked 9 months ago. Active 9 years, 10 months ago.

The application programmer can remain blissfully unaware of issues such as file endian-ness and data format. How do we handle problem users? Gavin H Gavin H 8, 2 2 gold badges 29 29 silver badges 35 35 bronze badges.
True, it's an incredibly basic question, but it's a legitimate question in response to seeing C code for the first time.
It is defined in sndfile. This function is useful in the following circumstances:. The error message is also correct, as we are using an unfittingly configured sndfile.
