#file: ogg-play.rb

`ogg123 #{ARGV[0]} > /dev/null 2>&1`

Espeak is a Text-to-speech program which I have used on Ubuntu. A sample of the audio can be found from my twittergram [twittergram.com]. Note: I made a few spelling mistakes in the audio, listen and tell me if you can hear them.

espeak -f hello_jr -s 120

Convert an mp4 file to avi, then to mp3 (including mixing the stereo down to mono). This code was executed from the command-line on Ubuntu 7.04.

mencoder video.mp4 -ovc lavc -vf scale=123:100 -oac lavc -o video.avi
ffmpeg -i video.avi -ac 1 audio1.mp3 

Converts all *.flac files in the current dir to mp3.

#!/bin/bash

for file in *.flac
do
	echo Converting $file
	flac123 -q --wav=- "$file" | lame - "$file".mp3
done

I used the following sox audio editor settings to do dynamic compression on voice.

sox in.wav out.wav lowpass 4000 compand 0.1,0.3 -60,-60,-30,-15,-20,-12,-4,-8,-2,-7 -2

py_s60 1.1.3 provide audio module which allow you to record sound.

import e32, audio

s = audio.Sound.open('C:\\test.amr')
s.record()  # start recording
e32.ao_sleep(5)  # do if for 5 seconds
s.stop() # stop recording


# the file is now created, ready to be played
s.play()

Using this code, I can record sound longer than
the 1 minute limit by Nokia's 'Recorder' program.

Update:
It can record in 'wav', 'amr','au'.
I can't play the file recorded with 'wav', though.
It seems 6600 has the problem with uncompressed 16-bit wave.
(It can play other wave files fine.)
