Audio(mic) volume issue

Recommended Posts

Posted (edited)

Hello, I'm new to this forum but not to Smule. I'm so frustrated!! I cannot sing a sustained note longer than about 2-3 seconds without my voice suddenly being suppressed. Help please, this has really got me down and depressed.

Using an Android smartphone and new apple earbuds.

Please provide more detailed information about the hard- and software you use. Otherwise it will be impossible to find a possible cause.

My Guess is that it is a compatibility issue between an Android Phone and Apple Ear Buds and Mic.

Once I accidentally plugged the Apple mike and ear phones to a Samsung Phone and found the pin was loose meaning lose contact. Does the Connecting pin have 2 lines(3.5mm - 3 Connector TRS) or 3 lines (3.5mm- 4 Connector TRRS Connector)

Greetings opentype and thank you for your response. I had actually hoped you would respond, as you seem to know your stuff. Following is the list of phone specs. Not clear on what else it is you would like, although I am happy to track any info down that may help. I'm just using my phone with Apple earbuds/mic and the most recent Smule Sing app.

 What I do know is that it specific to the recording function and only occurs with ear buds attached. I attempted to produce sustained sound for more than two seconds and the volume is automatically suppressed way down. I can sing another note and it jumps immediately back up but then down again, over and over. This is extremely frustrating. Is there anything I can do?

Thanks again openmic

It sounds like the mic gain is too low, so the automatic noise cancellation of Smule kicks in too early. 

I would try to use different headsets to see if they produce the same result. As RamKrish1012 said, there might be a problem with the headset or its connection.

If that doesn’t help, you can look into increasing the gain through the operating system. But I hardly ever Android, so I am not sure what options there are for your phone.

This is interesting as someone who struggled to get clean transparent recording with good voice without any sound-loss. I M not much aware what smule software does. But I have this feeling, from a no of perms n combos from 5 standard headphone/ earphones w mics in 3.5 mm singlre jack (4 pin) with 3/4 android phones, that once u plug in the jack the external noise is greatly cut n the earphones mic gets control, but if one doesn't use a headphone) earphone then the phones mic takes over leading to amazing recording quality it it's a closed room; I guess here the smule studio settings might be effective for gd recording.

Moreover from above trials n errors I found that headphone mics n inbuilt mics in android smartphones are powerful enough for smooth singing, whereas if one uses low cost mics in y-shaped splitter-adapters of headphone n microphone connected by a single 4-pin 3.5mm jack, the voice quality drastically goes down and no consistent uniform recording, the voices become high n lies that was very irritating. Want to hear from you all. Thanks.

Himanshu Currently I am using a gaming head phone which has no Mic and uses the Samsungs built in Mic. I was not very pleased with the outcome so I have spliced the standard android mic that comes with the ear plug to the Head Phone Cable so the Mic is located at the correct position and use a splitter to connect both to the Phone. Has worked OK so far but I am after even better and consistent quality. Am looking at Sennheiser MK4 Condensor Mic and a Sennheiser HD630VB head phones but then it is a very expensive option for hobby singers on smule costing USD $800 each..Others have suggested Bollinger. Will let you know when I finalise my optuons.
