The THPConv tool converts an ordinary wav file to THP audio data and can interleave it with THP movie data. The following restrictions apply however.
-
wavfiles must be non-compressed 16-bit PCM data.- Monaural (one channel) and stereo (two channels) files are supported.
If the wav file does not meet these requirements, the THPConv tool will output an error and stop processing.
Note: If the playback frequency is set to 48,000 Hz, Revolution will output the audio data at 48,043 Hz. If the frequency is set to 32,000 Hz, it will output at 32,028 Hz. To maintain strict synchronization between the video data and audio data when THP movie data is played, be aware of this characteristic of Revolution. In practical terms, when creating THP movie data, it is necessary to either convert the audio data playback frequency in advance so that it matches the Revolution's characteristics, or else use the audio library (AX) functionality during THP movie data playback to convert the audio data playback frequency.
When converting the audio data playback frequency in advance, run THPConv without specifying the -on option. There is no need to prepare a wav file with a playback frequency converted for Revolution.
When converting the playback frequency in real time on the Revolution, execute THPConv with the -on option specified. When playing THP movie data created with the -on option, use THPPlayerStrmAX.
Note: wav files having a playback frequency other than 48,000 Hz or 32,000 Hz can be specified for THPConv. When playing THP movie data created with such wav files, use THPPlayerStrmAX.
Further, when THP movie data is created with wav files having a playback frequency of 48,000Hz/32,000Hz, use THPPlayerStrmAX, if the playback frequency setting on the Revolution is different.
Note: If you want the THP movie data to contain more than one audio data set, make sure the number of channels and the playback frequencies for audio data sets are the same.
