Yet another question about replay gain...

[paulrhyan]

For years I've been using other tools to manage my collection. While I've known about MMW/MMA for some time; I've only recently started using MMW exclusively to manage my MP3 collection. For decades I've been 'normalizing' my MP3s with MP3Gain. To this day I still use it exclusively for setting volume.

Q1: I noticed in MMW most of my music does not have any values in the 'Track Volume' nor 'Album Volume' columns even though I know that the tracks have been analysed and gain has been applied by MP3Gain. Why?

Q2: I noticed in MMW some of my music has values in one or both of the 'Track Volume'/'Album Volume' columns yet the values in these columns are not the same values that MP3Gain reports. Why?
i.e.: in MMW, Black Label Society - Order Of The Black, all tracks have 'Track Volume' of around -10.5 dB and 'Album Volume' are all -11.3 dB. Now when I check MP3 gain, it shows Volume around 90.0 (90.0 dB is what I have the target volume set for) and Track Gain is shown as 0.0. There is nothing in Album Volume nor Album Gain columns as I rarely scan/modify the Album Volume.
Q2.1: Does MMW save gain edits to different types of tags than MP3Gain (V1 vs. V2 maybe...)?

Q3: Which volume data will be used by my music app. Right now I have my entire collection on my phone and I was using Poweramp but I've recently downloaded and paid for MMA(Pro).

Q4: I am thinking of using MMW to modify/change gain values of future music purchases. From what I've read, MMW uses the default of 89.0 (which I know is the industry standard). Can I change that value to 90.0?

Thanks in advance.

UPDATE:

I figured out Q2 and Q4. Still not sure about Q1, Q2.1 or Q3.

Thanks.

Hi,
Q1A: Can you please send me DL link for one sample file that have Gain In MP3Gain and not in MMW

Q2.1A: MMW uses Gain Indes standard depending on Track Format (FLAC, MP3,...).

Q3A: MMA uses Track Gain Volume Index and even if Index is not read on File scan it should be sent by MMW during Sync.
