Problem playing new audio tracks

I've put new MP3 songs on the K750i, and also recorded audio using the audio recorder. when coming to play, the phone says "sound cannot be played" and the length is "unknown". any idea why this is happening? thanks.

    The buttons on the right side of the phone, on the side control the volume. But that has nothing to do with the problem I have

    No, not at all. If I delete songs and put the ones that wouldnt work on, they work fine.

    Hmm ..
    Try updating your phones software, it might correct the problem.
    And you're sure all the files are MP3´s and not WMA or something ?
    The ones you recorded with audio recorder is that the built-in recorder on the phone ?

Why would the output sound level on a MP3 vary so much?

MP3 songs are recorded at different levels. Many modern tunes have been deliberately recorded loud by the record companies for maximum effect.
If you are recording the songs yourself some recording software has a "normalize" feature. This increases or reduces the volume of the track to a certain level. Especially useful when you have tracks at different levels. By the way this is how they get CD tracks to play at the same levels. So you don't have to turn up the volume or turn it down every time a new track plays.

Cant hear audio on tascam 2488i brand new to using it but i do understand how to record a track on my display screen i can see the audio i recorded but no sound what so ever i have my headphones plugged up...


Tascam Digital recording is an effective solution for broadcast-quality home recordings. The Tascam 2488 is a user-friendly tool and useful for home recording situations, especially when writing songs or cutting demos. It even has bus compression and processing for your final mix to give it that "mastered" feel. There are other recorders as well.

  1. Learn your gear. The Tascam 2488 DAW offers 24 discrete channels that can be recorded at up to 24-bit resolution. 16 tracks can be recorded simultaneously, via eight XLR balanced inputs and eith 1/4-inch unbalanced inputs. There are several high-quality built-in effects, such as reverb, delay, modulation, compression and a great tool for guitarists: amp and effect modeling. So you can simply plug directly into the console and get live amp tones.
  2. Record or program the rhythm tracks. Most Tascam products offer a large library of built-in drum loops to construct rhythm tracks, so you don't even need live drums just to get a song down. You can designate the tempo of your song from the transport located on the right side of the console; this is where you would use a variety of buttons to make edits, undo or redo and automate punch-ins
  3. Record your base rhythm instrument. Let's say a rhythm guitar. There is a dedicated guitar input located on the front of the console, and once you're plugged in you can use the aforementioned amp modeling features to dial up a sound.
  4. Record the remaining track or tracks. This could include bass, vocals, keyboards, horns or any other instrument. The process is always the same. Arm the track you wish to record on, hold in record and hit play, and the machine begins to record whatever you are playing. When you're done, hit stop. If you want to undo what you recorded, simply hit the undo button.
  5. Repeat these steps on any other instrument you want to record. Plug a microphone into one of the first eight XLR inputs, the first 4 of which have phantom power for studio condenser microphones, arm a track and record.

  • If you need to punch-in a section, you can automate it by dialing up the time in the song you wish to replace using the auto punch function. When you enable this and choose the time in the song you wish to record over, once you hit record and play it'll start the track a few seconds before where it begins the punch-in and it will only go into record when it reaches the designated time stamp.
Do not rush. Proper recording takes time and patience.

hopefully this can help

If I want to record let's say someone speaking for 90 min and burn 2 cd's , one 60min and the other 30 min from the one 90min recording , each one divided into tracks , how would I do this ?

If you want to burn a CD you have to make a master. For 2 cd's you have to make 2 masters, one for each recording.
The best way to handle this is to "create a song" for each speech giver and give each a name.This is because you can make only one master copy of a song before burning a Cd.

But another way is to :
1. Make a master of the first speech giver (who is on one track) and record to the Cd.
2. Make a new master of the second speech giver (on the other track) and record to Cd.
As long as you don't mind, the second mastering will overwrite the first one that you did, but then you already have burned a copy of that Cd!

No Valid Tracks or No Song Select

You cannot burn audio CDs from MP3 files. You have to burn MP3 files as a data CD and not as an audio CD. See excerpt taken from page 33 in the CDR420 user guide. "Prepares CDs that can be played on standard CD players. Compact Disc Digital Audio (CDDA) uses uncompressed PCM, .wav files. The CDR420 does not convert MP3 files to PCM so MP3 files are ignored if you choose AUDIO as the CD TYPE"

You have to "mix" the tracks to create a final work before saving the file.

Altering an mp3 track


If you simply want to overlap the voice, you can do that by recording using any free softwares available on internet (just google free recording softwares)
you can try, cooledit as well, one track will contain your file with play mode, one track with record mode (for your voice)
then start recording, it will play the song simultaneously with recording your voice.
After then, you have to save the mixdown.

other long way is, you have to get KARAOKE for that song (karaoke means, no vocals only music track) then you'll get the recorded song in good quality.

Hope this helps.

Downloaded songs appear in iTunes library but won't play on comp

I had exactly the same problem and followed the OP's solution, which worked, but I couldn't hear the track as it was being recorded.  So I tweaked the solution.  If you do the following, you don't have to keep changing System Preferences as you switch from record to listening:
Go to System Preferences, press the Sound icon, and click on "Sound Effects."  Then select the drop down menu and select "Play alerts and sound effects through selected sound output device" rather than the USB choice.  Then click on "Output" and select how you want to listen; I used speakers so I selected "Headphones" where the port is "Built-in audio."  Then click on "Input" and select the USB choice.  Now record a track and you can hear it being recorded through your speakers (or headphones).  When it's done recording and after the software transfers it to iTunes, you can play it again through your speakers without going to the preferences panel.
