A lav in the wrong place costs the dialogue editor an hour per scene. Placement is a post production decision made on set.

A sound report is not paperwork. It is the map that tells post which take works, which microphone to use and where everything lives.
Read the article — 5 minDialogue editing basics every filmmaker should understand
Dialogue editing is not noise reduction. It is a hundred small decisions about which microphone tells the truth of the scene.

Bitrate is a budget. The encoder spends it on the parts of the sound it thinks you will notice, and runs out earlier than you would like at low settings.

Your meters said minus one. The platform still turned you down by six. That gap is LUFS, and it decides how your work actually sounds to an audience.

Lossless and uncompressed are not synonyms. Understanding the difference is what lets you halve your archive size without ever touching quality.
Read the article — 6 minSplitting a stereo file into two mono files, and when you should
Half the stereo files on a shoot are not stereo at all. They are two unrelated mono sources sharing a container.
Read the article — 5 minAudio file formats explained: what to record, what to edit, what to deliver
Six formats, three jobs. Recording, editing and delivery each want something different, and picking wrong costs you either quality or a very long upload.
Read the article — 7 minNormalising audio: peak, RMS and loudness, and which one you need
Normalising to 0 dBFS is the default in most tools and almost never the right choice for professional delivery.
Read the article — 6 minSample rate conversion, explained without the maths
Resampling is not a setting, it is a calculation. Doing it twice, or at the wrong moment, is how audio drifts out of sync.
Read the article — 6 minHow to choose an audio file converter you can trust
There are hundreds of audio converters. Very few tell you what they did to your file, and fewer still keep it off their servers.

The audio inside your MP4 is already compressed. The only question is whether you make it worse on the way out.
Read the article — 6 minHow to rename multiple files at once, and what to check first
Every operating system can rename a thousand files in one click. None of them can undo it once the session has been saved.

Doing it once properly costs twenty minutes per card. Doing it later costs a weekend and you will still get half of it wrong.

Post production judges your day entirely by what the filenames and metadata say. Five minutes of recorder setup buys a week of goodwill.

One microphone, one channel. The rule is simple, and the exceptions are where the interesting work happens.
Read the article — 5 minWhy your poly WAV shows Track 1 to Track 8, and how to get real names
Boom, Lav Marie, Plant Kitchen. Or Track 1, Track 2, Track 3. The difference is one metadata block and a recorder someone bothered to configure.

Most libraries are not badly organised. They are organised twice, in two incompatible ways, by the same person eighteen months apart.
Read the article — 7 minWhat a WAV metadata editor actually edits
A WAV is not just samples. It carries chunks of text and timing that decide whether your file syncs, sorts and searches, or just plays.
Read the article — 6 minA file naming convention for audio that still works in three years
Every naming convention works on day one. The test is whether it survives version 14, a second recordist and a client who renames everything.
Read the article — 6 minHow to rename audio files in batch without breaking your session
The rename itself takes four seconds. The relink that follows can take a day. Do it in the right order and it takes neither.

Category, subcategory, CatID, synonyms. Four columns, one spreadsheet, and a lot of people who give up on the second scroll.
Read the article — 6 minFLAC to WAV: when lossless still needs converting
FLAC to WAV is the rare conversion that costs you nothing in audio quality. It can still cost you metadata if you are careless.
Read the article — 4 minUCS explained: the naming convention that finally made sound libraries searchable
Two sound designers, two naming habits, zero shared search results. UCS is the community standard that fixes it, and it takes an afternoon to learn.
Read the article — 7 minWAV vs AIFF: does the choice still matter in 2026?
Same audio, different container. The decision comes down to metadata and who receives the file.

The marketing says you can stop riding gain. The physics says something slightly more nuanced.
Read the article — 6 minConverting M4A to WAV for editing, the right way
Phone recordings, voice memos and camera scratch audio arrive as M4A. Editors want WAV. Here is what happens in between.
Read the article — 5 min48 kHz vs 96 kHz: which sample rate should you actually shoot at?
The honest answer for most productions is 48 kHz. The interesting part is the small set of cases where it is not.

Three ways to sync, one right answer for each situation, and the preparation that makes all three faster.

Most sync failures are not sync failures. They are frame rate misunderstandings, and you can spot them before the assembly starts.

Every professional WAV carries a hidden layer of production data. Knowing what is in there saves hours of guesswork in post.
Read the article — 7 minWhat is a poly WAV, and why does your editor keep asking for mono files?
Boom, lavs, plants and a mix, all inside one file. Poly WAVs are the default on modern field recorders, and the first thing many post workflows reject.
