Detailed Description
Routines for interaction with wave files.
Function Documentation
| wave* wave_new | ( | int | i_size | ) |
creates new wave object with size i_size.
- Parameters:
-
i_size size of wave array (bitrate x duration)
- Returns:
- wave object (free with wave_free)
| void wave_free | ( | wave * | i_wave | ) |
frees wave object.
- Parameters:
-
i_wave wave object
| wave* wave_load | ( | char * | i_path, |
| int | i_sec | ||
| ) |
loads given wave file.
- Parameters:
-
i_path file path i_sec duration to read from wave file
- Returns:
- wave object
| void wave_save | ( | wave * | i_wave, |
| char * | i_path | ||
| ) |
saves given wave file.
- Parameters:
-
i_wave wave object i_path file path
| fft* wave_fft | ( | wave * | i_wave, |
| int | i_freq | ||
| ) |
fast fourier transformation of wave object to a fft spectrum.
- Parameters:
-
i_wave wave object i_freq frequency range
- Returns:
- fft spectrum (only sound spectrum is defined)
| void wave_play | ( | wave * | i_wave | ) |
play back wave object on sound card.
- Parameters:
-
i_wave wave object
