[Asterisk-Users] Digium TheVoice recordings' sound terrible
A customer has ordered some voice prompts from Digium's TheVoice online store. They say the recordings' sound was good when they listened to it on their Windoze boxes. However, then Asterisk is playing back the recordings, the volume is far too high and they sound really bad. This is particularly noticeable since the IVR menu mixes those ordered recordings with recordings that are already part of the Asterisk distribution. The volume of the included recordings are much lower and they sound much better than the ordered recordings. I wonder why Digium would deliver recordings that differ so much from the included set of recordings. However, the format the customer ordered was WAV, whereas all the included recordings are of course GSM. Has anybody had similar experiences? I tried to convert the WAV files to GSM using sox but since I don't know what parameters are best in this case, the results weren't satisfactory. Any suggestions? thanks rgds benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan. NB: Spam filters in place.

Things that are productive. 1. I am sure there are free programs that will allow you to adjust the files to sound more like the originial recordings as well as converting them to gsm. Do some searching and learning and fix it yourself. Mail Digium directly so that they are aware of the problem and can correct it for future recordings. Possibly something like this http://www.softpicks.net/software/Complete-Audio-Converter-Lite-1470.htm 2 . If you dont want to go through all of that, kindly ask Digium to have the files fixed for you. I seriously doubt they have their own sound stage and most likely outsource this type of business. Chances are the people they outsource the business to are experts and have sophisticated equipment to do this with very fast turn around time. 3. Email thousands of people that will probably ignore you or not know the answer (with the exception of myself). I would choose number one.

That will convert WAV files to GSM and adjust the volume for you during the conversion process. -- _/ _/ _/_/_/_/ _/ _/ _/_/_/ _/ _/ _/_/_/ _/_/ _/ _/ _/ _/_/ _/ K e v i n W a l s h _/ _/ _/ _/ _/ _/ _/ _/_/ kevin@cursor.biz _/ _/ _/_/_/_/ _/ _/_/_/ _/ _/

Any suggestions?Benjamin, Don't know if this helps you or not, but this is taken right from Jtodd's wiki page. **my disclaimer** Might want to backup your sounds before doing this though. #!/bin/sh tmpfile=/tmp/rescale$$.wav for i in *.wav; do scale=$(sox $i /tmp/foo.wav stat -v 2>&1) if [ $scale != "1.000" ]; then echo -n "Rescale $i..." cp $i $tmpfile sox $tmpfile -v $scale $i echo fi done The wiki page is at http://www.voip-info.org/tiki-index.php?page=Asterisk%20sound%20files Hope this helps, -Chuji

[Asterisk-Users] Digium TheVoice recordings' sound terrible
Greetings Ben, If you have not gotten your answer yet; Converting audio files from WAV to telephone 3000HZ will always cause a degradation of the audio quality. Could you elaborate on " they sound really bad " please? I would take the .gsm files that Digium produced or converted from the .WAV files and play them back on the Windows machine and then compare that quality to the WAV on the Windows box. The .gsm should sound the same on the windows box as on the phone. If the quality is worse then contact Digium. I used http://www.audioi.com/ 'Audio Converter and Ripper' to convert .wav to .gsm. On playback the .gsm has good fidelity. On the phone, we are using a Cisco 7200 and not Asterisk for play back, the quality is the same. Make sure you are converting correctly, 16bit 8000hz Mono, for gsm g729. 1. convert the .wav to .gsm using "Audio Converter and Ripper", shareware. 2. play the .gsm and compare to the .wav. 3 play the .gsm and compare to results from the phone. 4. if there is much difference check the phone AUDIO CODECS in asterisk, you might be converting from GSM to G729 on the fly ( I know, technically only a slight difference.) Do you have the G729 license from Digium installed? 5. make sure the conversion process was done correctly. 16bit, 8000hz per sample, Mono.
