There is a new beta available. If you already downloaded a beta, you will =
get notified when you start Book Port Transfer. If you have not been beta =
testing and you wish to try this out, you must have the beta firmware, =
too. The beta firmware is at www.aph.org/beta/bpfw_beta.exe and the new =
software is at www.aph.org/beta/bp_beta.exe.
Here are the details about this new revision of the software:
If the Send Audio Files as Music option is not checked, the Options dialog =
offers some advanced functionality that let you alter the speed of the =
audio file's playback. These functions are accessed with the Audio =
Options button.
Audio Options
Experienced audio listeners will quickly desire a means of speeding up the =
playback of spoken word audio content. Since there is not a way to =
perform this speedup with commands on the Book Port device, the transfer =
software offers a method of using your PC to perform the speedup then =
sends that reduced file to the device. There are two settings you can use =
to both reduce the size of an audio file and make the listening experience =
less time-consuming.
The audio compression settings currently work with all audio files except =
those from audible.com.
Time Compression
The Compress Time checkbox determines whether or not Book Port Transfer =
attempts to alter your file to make listening faster. If this control is =
checked, the Advanced Audio Options dialog contains a Time Compression =
Speed edit box where you may enter a number between 1 and 3 to specify how =
fast the playback speed should occur. The values you enter in this =
control dictate the aggressiveness of the software's time compression =
routines. Using a value of 1.5, for example, makes the resulting file =
flay at a 50% increase in the rate of speech. The number 2 specifies =
double the rate, and 3 specifies a rate three times normal.
Compress Pauses
The pause compression features of the transfer software provide a =
convenient means of reducing the amount of space between sentences, =
sections, and other divisions in the audio. If the Compress Pauses =
checkbox is checked, the software eliminates a percentage of any pause it =
finds that is longer than a minimum pause length that you specify.
The Compress By edit box lets you type a percentage value the software =
uses to reduce pause lengths. If you entered 50 in this box, the software =
reduces the length of each pause it finds by 50 percent.
The Ignore Pauses Less Than control lets you enter a value in milliseconds =
the software uses as a minimum pause length. If any pause the program =
finds is less than this length, the software ignores that pause.
Previewing the Effects of Compression
Once you have set advanced audio options, you may wish to preview the file =
before sending it to the device. The Preview window plays the file with =
the new time compression settings. Unfortunately, the preview window does =
not currently offer a means of testing the pause compression setting.=20
